Changelog

This page summarizes the English release notes for the local Android app.

For full localized notes, see the Android app repository changelog.

OpenVitals is a Kotlin app. It was rebuilt on Flutter in 2.0.1 and migrated back to Kotlin in 2.5.0, so entries between those two releases describe the Flutter implementation, and everything before and after describes the Kotlin one. (2.0.0 was prepared but never published, so 2.0.1 carries everything since 1.9.0.)

2.6.4 - 2026-08-13

This release is about numbers that were technically correct and told you nothing: a battery that charged a broken night like a perfect one, a month of weight drawn as near-identical coloured dots, a nutrition total nobody eats by, and a step count short of what the watch had actually recorded.

Body Energy tells a good night from a bad one. Overnight charge now reflects how well you slept - sleep efficiency, time spent awake, and the deep and REM share of the night - and not only how long you were in bed. Two eight-hour nights of very different quality used to land within a few points of each other; they now sit about fifteen apart. An ordinary night charges exactly what it did before, the effect is capped so no single night can undo hours you actually slept, and a sleep source that records no stages is left alone.
Weight is a line, not a calendar. Week, month and year now draw body measurements as a trend line on a scale fitted to your values, instead of a calendar of coloured dots. A calendar shades a day by how big its number is, which says nothing about a weight that lives inside a two-kilo band.
Nutrition shows what you eat in a day, not in a month. Over a week, month or year each nutrient tile leads with the daily average and keeps the period total underneath. A new Nutrition setting chooses whether the average divides by the days you logged food or by every day of the period.
Fixes: Garmin step counts no longer come up short - overlapping step records were being partly discarded, so a day could read 889 steps when the watch had recorded 1,007; an entry list keeps how far you expanded it after you swipe an entry away; maximum heart rate is no longer invented from a quiet fortnight, and an estimated figure now says it is estimated; the cardio load target no longer reports impossible percentages; and chart date labels no longer arrive cut in half.

2.6.3 - 2026-08-12

This release is about the watch feeling paired, not just synced: a Garmin watch can now stay connected whenever it is in range, and that held link carries live readings, weather, your calendar, find-my-phone, and GPS ephemeris - all without the app gaining any internet access.

Your Garmin watch can stay connected. A new Stay connected switch keeps the Bluetooth link open whenever the watch is in range, the way the vendor’s app does. With it on, an optional Live readings switch streams the watch’s current heart rate and step count - shown live on the watch screen and the dashboard. Both are off by default.
A watch tile on the dashboard. The most recently synced watch, with its battery, last sync time, and a sync button. While live readings stream, the tile shows the current heart rate and steps instead.
Weather, calendar, and find-my-phone on the watch. The weather glance is answered from a weather app on the phone (Breezy Weather is the tested one). The calendar glance can show the phone’s upcoming events, off by default behind its own permission. And the watch’s find-my-phone rings the phone, even when silenced.
Faster GPS fixes. Import a satellite prediction (ephemeris) file and the phone hands it over when the watch asks, turning a minutes-long cold GPS fix into seconds. Nothing is downloaded.
Grant all permissions at once. The first onboarding screen gets a Grant all button that requests every category in one dialog.
Sleep score rebuilt on sleep-science pillars. Duration, quality, and overnight HRV recovery are scored using published sleep guidance, with age and night HRV feeding the score, recovery, and the dashboard.
Fixes: cardio load and intensity minutes read workout heart rate instead of falling back to movement; body tiles open their own metric screens directly; the syncing banner is no longer clipped; a smartwatch added through the sensors flow stays a plain sensor; diagnostics exports include raw process logs.

2.6.2 - 2026-08-08

This release lets a reading into the app that no wearable took: HRV can now be logged by hand, and every hand-logged vitals reading can carry the moment it was actually taken.

Log HRV manually. Heart rate variability joins the Log screen: enter an RMSSD value in ms and it is written to Health Connect, feeding the dashboard tile, the HRV screen, and baselines like any watch reading. Your own entries can be edited and deleted from the HRV day view; the tile can be removed in the Log screen’s edit mode.
Pick the time on new entries. Every vitals entry form - blood pressure, SpO2, respiratory rate, body temperature, HRV - now offers date and time pickers when adding, not only when editing. A reading taken this morning can be logged tonight under its real clock; the pickers default to now.
Fixes: switching days on the dashboard answers instantly - the date flips at once, tiles show a loading state instead of the previous day’s numbers, and the rings sweep in exactly once with the right values; the small weekly cardio tile no longer says “Loading” forever next to the cardio ring; returning from a metric screen keeps the widget page and scroll position; the hydration day graph no longer ends in a dot - dots mark entries only; a sleep window set within one day (such as 00:00 to 12:00) files each night on its own date.

2.6.1 - 2026-08-06

This release puts a navigator next to the recorder: with a CoMaps build that shares its navigation, a GPS recording shows the guidance you are actually following while OpenVitals keeps recording. CoMaps plans and navigates; OpenVitals reads and records.

Live CoMaps navigation while recording. The next turn floats over the live map, the planned route is drawn point-for-point on the offline map with turn arrows and a destination flag, and the location dot becomes a compass arrow that points where the phone points. With the integration on, Start becomes a doorway - set the route up in CoMaps or dismiss the guidance card, then start. Guidance shown during the ride can be kept with the saved activity - on this device only, never in Health Connect. Off by default under Settings > Activity recording.
One launcher icon. The release build ships the artwork the debug build had; debug keeps the shape and differs only in colour.
Fixes: with 3-button system navigation the bar no longer covers the bottom of screens; heart and vitals tiles open their own metric screens instead of a shared overview; the swipe-to-delete red no longer shows through entry rows at rest; one reload shows one indicator, and dashboard widgets replay their animations only when a reload actually brought new data.

2.6.0 - 2026-08-05

This release is about the two conversations your health data has outside the app: with your doctor, and with you. A PDF report you can hand across a desk, menstrual cycle tracking that lives entirely in Health Connect, and blood-pressure logging that captures what clinicians actually ask about a reading.

Menstrual cycle tracking. Log period flow, spotting, sexual activity, ovulation tests, cervical mucus and basal body temperature - one category at a time, each its own Health Connect record. Period days derive from your flow entries, and cycle statistics predict the next period; when cycles vary too much for an honest prediction, the app says so. Cycle data stays a separately granted permission category and is stored only in Health Connect.
Health report export (PDF). Pick metrics, detail level and range, and OpenVitals builds a PDF on the device to share or save - charts, statistics and tables per metric, and clinical sections where the data has more to say: blood pressure with separate systolic/diastolic statistics and meal-context averages, glucose by relation to meal with fasting first, workouts by activity type with the full session list, and sleep with bedtime/wake-up averages and the stage mix. The report states its own gaps in print.
Richer blood-pressure logging. Optional dropdowns for when the reading was taken, body position and cuff location, plus a collapsible guide with the standard home-measurement protocol.
Distance backfill from steps. Opt-in under Activities: your stride length fills daily distance only for days that have steps and no distance from any source; derived records are marked and removed if you turn it off.
Portuguese added, and Spanish, Italian, Estonian and German are complete again at 100%.
The dashboard keeps tiles with recent history. A tile only sinks when its metric has no data today and none recently - Sleep no longer drops before tonight - and a “Sort empty tiles last” toggle makes it a choice.
Fixes: year-long heart-rate reads are chunked so they cannot come back empty; duplicated blood-pressure records count once in the report; cycle screens allow screenshots; the base unit option is named “System” everywhere.

2.5.0 - 2026-08-04

OpenVitals is native Kotlin again. Every feature the 2.x line added has been rebuilt on the Android-native app; your data and settings from the previous version are imported automatically the first time you open it.

Smartwatches sync through Health Connect. OpenVitals does not pair with watches: Gadgetbridge or your vendor’s app syncs the watch into Health Connect and OpenVitals reads everything there - steps, heart rate, HRV, sleep and workouts - with the original source shown on each record. Bluetooth sensors are unaffected and still stream live into recordings.
Sync health data with another phone over Bluetooth. Both phones stay offline - no account, no internet at any point - and records keep their original source across the transfer.
Import health data from CSV files through a guided wizard that maps your own columns.
Units that follow your device. The unit setting defaults to Android’s measurement-system preference, and every quantity can override it on its own.
Sturdier reminders, quick-add from the notification, GPS-free recording, a guided heart-rate recovery test, TCX and indoor-workout import, more accurate elevation, and a long list of fixes - see the app repository changelog for the full notes.

2.4.0 - 2026-07-28

Onboarding is rebuilt from the ground up, the dashboard stops nagging about permissions, and the whole app gets a quiet visual tune-up: consistently outlined icons and Material 3 text spacing.

Onboarding is now a four-step guide. Permissions are grouped the way Health Connect itself groups them - Activity, Body measurements, Nutrition, Sleep, Vitals - so the row you tap and the system dialog it opens carry the same name. One tap per category asks to read and to save, so entries you create in OpenVitals go back to Health Connect. Only Activity and Sleep are required to start; everything else is optional and can be added later from Settings.
Mindfulness and cycle tracking are opt-in steps. Mindfulness stays off unless you switch it on - some Health Connect versions crash their own permission screen when asked for it, so OpenVitals requests it alone, where it can’t take anything else down. Cycle tracking is its own step with a plain description of what it covers, and a Not now.
Exercise routes get a walkthrough. Reading route maps is the one permission Android hides behind Health Connect’s Additional access page, out of reach of any app. If it’s still missing after the Activity grant, the last step shows the three taps that finish it, with a button that lands one tap away.
The dashboard no longer asks for permissions. The two prompt cards that used to stack on the home screen right after onboarding are gone. A metric without access simply shows no data; screens ask at the point of use instead.
Icons are consistently outlined - the same glyph no longer appears filled on one screen and outlined on another - and text spacing now follows Material 3, restoring the letter-spacing the body and title styles had silently lost in the Flutter port.
OpenVitals never asks for a permission your device cannot grant. Requests are filtered against what the installed Health Connect provider defines and what the app itself declares - the combination that could crash the system Health Connect app on some de-Googled ROMs, locking users out of granting anything at all. This also fixes phone-to-phone sync demanding a skin-temperature write permission that could never be granted.

The permission model is versioned: existing installs pass through the new onboarding once, then continue to the dashboard as usual. Nothing already granted is asked for again.

2.3.2 - 2026-07-25

A small release for the activity screen: the offline route map stops freezing and crashing, PMTiles packs actually draw their map, and the route export from the pre-Flutter app is back.

Export a workout’s route again. The route card on an activity got its buttons back from the pre-Flutter app: open the route in a map app, save it as GPX, or save it as KMZ. Files are named after the activity and its start time, and the save goes through the system save dialog so you pick where it lands.
Offline maps no longer freeze the activity screen - or crash the app. With a Mapsforge pack active, scrolling to the map could hold the whole screen for seconds while tiles were prepared, and past five seconds Android kills the app as unresponsive. Tiles are now read and prepared in the background, so the screen stays smooth while the map draws in.
PMTiles packs draw their base map again. An imported .pmtiles pack rendered nothing but the plain background behind the route; the vector base map now appears as it should.

2.3.1 - 2026-07-24

A polish release about honesty at the edges: the day boundary, the year view, and the hours your tracker spends off your wrist. Widgets stop freezing overnight, mornings show last night’s vitals instead of “No data”, Body Energy keeps living while the watch charges, and a Garmin Edge can now be a live sensor and a sync device at once.

A Garmin Edge can be two things at once. A bike computer now broadcasts as a live sensor during a recording - heart rate, speed, cadence, power, the way a strap does - while still syncing its recorded rides afterwards. WearOS smartwatches are also recognised as their own device type, with a Health Connect sources card in diagnostics.
Widgets stop freezing overnight and ask for what they need. The refresh alarm survives Android’s battery saving, placing a widget offers the “Alarms & reminders” permission that keeps refreshes on schedule (declining keeps the widget), and widgets refresh the moment a watch sync or an Apple Health import lands new data.
Body Energy keeps living while the tracker is off. Once the day has shown any data, baseline metabolism keeps draining through the gaps, and a walk recorded by the phone’s own step counter drains too. Untracked days hold steady rather than sliding to zero.
Mornings show last night. HRV, resting heart rate, respiratory rate, SpO2 and skin temperature read from your night window, so the dashboard has your overnight values at breakfast instead of “No data” until the first daytime sample.
Caffeine and streak fixes. The bedtime projection describes the night ahead, the dashboard tile shows the caffeine active right now with today’s intake beneath it, goal streaks survive midnight until the day genuinely fails, and a drink just before midnight still anchors the hydration reminder schedule.
The Calories year view tells the truth. No more doubled and missing days around the clock changes, no phantom kilocalories in empty years, no piling up reads until the screen hangs when paging quickly through years.
Garmin sleep stages sit where they happened, intensity minutes count the whole week toward the weekly goal, and every top-level screen survives the largest text size.

2.3.0 - 2026-07-22

Note: The direct watch connectivity described below (watch pairing, sync, alarms, and on-watch settings) has since been removed from OpenVitals. Watches now sync into Health Connect through Gadgetbridge or the vendor’s app — see Smartwatches. Bluetooth LE sensors and phone-to-phone sync remain.

The biggest release so far. OpenVitals can now read a Garmin watch directly over Bluetooth - no Garmin account, no Connect app - and copy your health records to another phone the same way. Body Energy gets a plot on your home screen, sleep gets a night window you set yourself, and the Calories year view that used to take half a minute now opens straight away.

Garmin watch sync. Pair a Garmin watch and copy what it recorded straight off the wrist over Bluetooth. Sleep, heart rate, HRV, VO2 max, SpO2, respiration, steps, distance and workouts go to Health Connect; the measures Health Connect has no place for - stress, Body Battery, intensity minutes, training readiness, recovery time and training load - are kept in the app and shown on a Watch data screen. Nothing goes through Garmin’s servers, and the app still has no internet permission.
Your watch’s alarms and settings, from your phone. Switch alarms on and off, retime, rename, add and delete them, and browse the watch’s own settings menus - all read live from the watch, in the language the watch is set to. There is also a Find button to make the watch alert when you have mislaid it.
Sync with another phone. Copy Health Connect records to a nearby phone over Bluetooth, with no account and no internet. All 41 record types are supported, the two phones pair with a code you confirm on both, and a report tells you exactly what moved.
Body Energy on your home screen. The Body Energy widget draws the day’s curve beside the score. Sleep also gets a night window you set yourself, replacing the fixed range modes.
Much faster everywhere. The Calories year view opens immediately instead of taking up to half a minute, the dashboard reads its metrics concurrently, the charts stop repainting every frame, and a recording no longer writes every sensor event to disk as it arrives.
Fixes. A partly-staged night draws whole and merged nights open their detail; a day’s steps are no longer doubled by syncing twice; reminders survive a long absence; reading the log and importing a route file no longer freeze the app; floors, elevation and wheelchair pushes land in the right period; and widgets show fresh data after the background isolate is reused.

2.2.8 - 2026-07-20

This release adds heart-rate recovery, rebuilds hydration and mindfulness reminders so they survive an app update rather than only a reboot, and ties the numbers on screen to the research behind them. It also fixes a Calories screen that could hang and a 30-day calendar that only drew part of the month.

Heart-rate recovery. A guided test measures how quickly your heart rate falls in the minute after exertion. Recovery also appears on a workout, and is tracked over weeks and months, read from the samples Health Connect already holds. It is measured only from a deliberate test now, so a heart rate that rose after exercise is no longer misreported as a recovery.
Reminders that survive an app update. Hydration and mindfulness reminders were rebuilt from the ground up so they keep firing after every update, not just after a reboot. Hydration nudges now anchor to your last drink — the countdown resets each time you log one, and is skipped if you drank recently — and fire on the exact minute when you allow exact alarms.
Every number shows its science. The sleep, daily-readiness, body-energy, cardio-load and caffeine screens carry tappable links to the research behind their calculations. The sleep goal also counts only the time you were actually asleep, so awake time inside a sleep session no longer counts toward it.
Tap a day in the month calendar to open it. On any metric’s month view, tapping a day drops you straight into that day’s detail. You can also read the time off the sleep hypnogram by scrubbing across it, and it steps aside when a night is only partly staged instead of drawing a misleading graph.
The Calories Day view could hang on its loading spinner forever on some phones; it no longer does. The “Last 30 days” calendar now shows all thirty days across a month boundary instead of only the part that fell in one calendar month, and a past 30-day window is titled by its dates rather than a single month it mostly is not in.
The sleep score and sleep efficiency detail screens are reachable again, and the sleep day view no longer draws the hypnogram over its own labels, drops stats that did not belong there, and calls the duration “time in bed”.
Recording fixes. A workout could fail to save because it never asked to write its own heart rate; a session could end before its last sample; and your own edits now show immediately, writing through the daily cache instead of waiting for the next sync.
Spanish, German, Estonian and Italian are fully translated.

2.2.7 - 2026-07-17

A maintenance release that brings back editing and deleting your own entries, makes large Apple Health imports dramatically faster with a working report at the end, and fixes the sleep chart, the workout rest bell and the hydration widget.

Editing and deleting the entries you logged in the app works again. Swipe a hydration, nutrition, caffeine or mindfulness entry to delete it, tap the pencil to edit a hydration or mindfulness entry, and edit or delete an activity from its detail screen. Only entries OpenVitals wrote are editable; records from other apps stay read-only. These were lost when the app moved to Flutter.
Large Apple Health imports are dramatically faster. The per-batch duplicate check is bounded to the batch’s own time window instead of scanning your whole history on every batch, which grew slower and slower as the import went on. The report you can copy or save when it finishes works again too: a big export’s report reaches tens of megabytes, which the previous store could not hold, so it is now written to a file.
The workout rest-timer bell ducks your music or podcast for the chime instead of stopping it, then restores it to full volume.
Logging a drink from the 1x1 home-screen widget clears an active hydration reminder, the same as logging it inside the app.
The sleep chart no longer looks broken. The day view no longer draws its stage graph over its own lane labels at larger system font sizes, and a day that includes a nap keeps the same rounded bars as every other day in the month view.

2.2.6 - 2026-07-17

The largest release since the Flutter rebuild. Large Apple Health exports import without running out of memory, Garmin FIT files import from a folder, and the long-range overviews are much faster.

Importing a large Apple Health export no longer runs out of memory. The export is now read a piece at a time instead of loaded whole, so a multi-gigabyte file that used to crash a minute or two into the analysis now imports. Re-importing the same export no longer creates duplicate entries either — the identifier each record is matched on is stable again, so records you already imported are recognised instead of written twice.
Body Energy. A new screen that scores how much energy your body signals support today, from recovery-side inputs — sleep, heart-rate variability, resting heart rate, physiological stress, temperature, hydration, nutrition and mindfulness — on a 0-100 scale, and calibrates to how you say you feel.
Garmin FIT files import from a folder. Point the importer at a Garmin export and it reads sleep, heart-rate variability, resting heart rate and basal metabolic rate. Files it cannot map are reported as skipped rather than failing the whole import.
The Year and other long-range overviews are much faster. They keep a local cache of daily summaries and update only what changed since the last sync, instead of re-reading a year of records every time you open them.
Sleep is more accurate. Daytime naps are separated from the night, and overlapping sessions recorded by more than one source — a watch and a phone logging the same night — are de-duplicated instead of double-counted.
Charts pinch to zoom on every range, and the zoom keeps working while you scroll the page.

2.2.5 - 2026-07-14

The download now says which phone it is for.

The APKs on the releases page are named after the architecture they are for. 2.2.4 split the download in two, one per architecture, but named them after an internal version code, which tells you nothing about which one your phone wants. They are now clearly labelled arm64-v8a and armeabi-v7a. Take the arm64-v8a one unless you know your phone is an older 32-bit device; F-Droid and the Play Store still pick for you. The app inside each APK is byte-for-byte what 2.2.4 shipped.

2.2.4 - 2026-07-14

Half the download, and none of it for a phone you do not have.

The APK no longer carries libraries for architectures your phone cannot run. Every download held both builds of the app — the 64-bit one and the 32-bit one — so whichever phone you have, half of what you downloaded was for somebody else’s. It also held a third set of libraries, for x86_64, that could never have run at all. There is now one APK per architecture, containing only its own, and the download falls from 60 MB to 34. The releases page offers two APKs: nearly every phone made in the last decade wants the arm64-v8a one, and armeabi-v7a is there for older 32-bit devices. F-Droid and the Play Store pick the right one on their own.

2.2.3 - 2026-07-13

The last of the Google out of the build.

Google’s dependency blob is no longer stamped into the APK. Android’s build tools quietly attach a block to every APK they sign: a list of every library the app was built from, encrypted with a Google key so that only the Play Store can read it. It survived the removal of Google Play Services because it is not a dependency at all — it is added at the moment of signing, after everything else is done. It is gone from the APK now. The app bundle uploaded to Play keeps it, because that is the one place it is actually read.

2.2.2 - 2026-07-13

The second half of what 2.2.1 started. 2.2.1 took Google’s proprietary code out of the app so that F-Droid could build it; this one makes the build reproducible, which is what F-Droid needs in order to ship it.

The app now builds bit-for-bit identically on someone else’s computer. F-Droid does not take our word for what is in the APK: it builds the app from source on its own servers and compares the result, byte by byte, against the release published here, and only distributes the copy we signed if the two match. Everything already matched except twenty bytes in one library: a build-id, a hash the linker stamps in that silently records the paths of the machine that did the build. It is no longer stamped, so the app you download is provably the one the source produces.

2.2.1 - 2026-07-13

A packaging release, and a short one. OpenVitals no longer contains a line of Google proprietary code, which is what it takes for F-Droid to build it.

Google Play Services are gone from the app. The location plugin depended on Google’s proprietary location library, and the app never used it. Route recording has always asked Android’s own location manager for satellite fixes directly, because Google’s fused provider quietly mixes in network and wifi positions that are not the GPS readings a recorded route is actually made of. So the library sat in every build being nothing but a dependency, and it was the one thing standing between OpenVitals and F-Droid, whose scanner refuses to build an app that carries it. Nothing about recording changes.

2.2.0 - 2026-07-13

This release is about the charts. Every one of them was a picture you could look at and not ask anything of: you could see that the line went up somewhere in the afternoon, and no way to ask when, or how much. The numbers were in the data and never on the screen. They answer now.

Drag a chart to read it. A crosshair follows your finger, a ring marks the sample, and a tooltip gives the value and the time it was taken. It snaps to a reading that was actually measured, never to a point the app invented between two of them — the curve between two readings is an interpolation, and a tooltip may only report a number that was really recorded.
The caffeine curve has a scale at last. It drew the decay of caffeine in a body with no axes and no way to tell when any of it happened. It now reads milligrams down the side and midnight to midnight along the bottom, with a dashed line for the level to be under by bedtime, and a tick under each drink, so every rise sits above the drink that caused it.
Charts draw themselves in — the line left to right, the bars up out of the axis, the ring round to its value. It is not decoration: it is the chart telling you which way to read it. If you have asked your phone to reduce motion, they are simply there, fully drawn.
Charts load into a chart-shaped skeleton instead of a spinner, so the page no longer jumps when the data arrives. And an empty chart now looks like an empty chart, with an icon and a sentence, instead of a stray line of grey text.
New chart colours. Eight of the seventeen metric accents were too faint to see against the background — gold scored 1.59:1 where 3:1 is the floor for a graphical object you are meant to see. Every accent clears it now, and keeps the hue it has always had: steps are still green, water is still blue, the heart is still rose.
Body Energy could draw a score above 100, or below the lowest reading of the day, on a score defined as 0 to 100. The curve can no longer leave the range of the data it was drawn from, and it gained the 0-100 scale it never had.
An axis could label two different heights with the same number, and a chart could fill the area under a line that was not there. Both fixed.
German, Estonian and Italian said route import took GPX/KML/KMZ, while the app has read TCX since 2.1.0 — the one file type an indoor athlete would look for was the one those languages said it could not read. German, Spanish, Estonian and Italian are now complete.

2.1.0 - 2026-07-13

This release is about the activities the app was throwing away. A treadmill run, a trainer ride, a strength session — anything recorded without GPS — was refused at the door as a broken file. It was not broken. It had no route, and the app had quietly decided those were the same thing.

Import a whole folder of FIT files. Pick the folder; every FIT file inside it is imported, including the ones in the sub-folders where a watch buries them. A file that will not read fails on its own and the rest of the folder carries on.
TCX files are now read — the format Strava and Garmin actually export an indoor activity as, and one the app could not open at all. It is XML, so it used to fall through to the GPX reader, which found no track and blamed the file.
Indoor activities could not be imported. A FIT file records total calories and has no active-calorie field, so the app filled the blank with an estimate — and stood that estimate next to the number the file had actually measured. A treadmill run arrived as 226 estimated active calories against its own recorded 208 total, and Health Connect refuses a record whose total is below its active. A guess was allowed to contradict a measurement. It is now estimate both or estimate neither.
An indoor bike ride imported as a run. The app decided what an activity was by mashing the sport, the name and the file name into one string and testing “run” before “cycling” — so Indoor_CyclingiSmoothRun.fit was read as a run, and a 27 km ride was saved as one. The file’s own sport is now asked first, and on its own. A stationary bike is also an activity type of its own at last, so a trainer ride is no longer saved as an outdoor one.
A GPX with no locations in it was refused. Real exporters write indoor sessions as track points carrying a time, a heart rate and no coordinates at all — 1,931 of them for a strength session, in one of the files this was fixed against. The session was in the file the whole time: the timestamps give the start, the end and the duration, and the extensions give the heart rate.
A GPX with a heart rate in it lost the heart rate, and imported as a bare line on a map.
Activities show an elevation profile — where you climbed, not just how much. Health Connect stores one total for a session, so it can tell you that you climbed 240 m and never where; the profile is drawn from the route’s own altitudes.
A speed graph appears even when the device recorded no speed, which is most watches. It is rebuilt from the splits, which knew each segment’s distance and duration all along, and drawn as a step — one flat run per split, because that is the resolution those numbers really have.

2.0.4 - 2026-07-12

The app’s insides were rebuilt this release, and the rebuild is what found the bugs. Moving every calculation out of the screens that were doing it mid-draw put a lot of arithmetic side by side for the first time — and several numbers, it turned out, disagreed with each other.

The sleep card called your watch’s recordings “hand-typed”, and never noticed the ones that really were. Health Connect labels how a record was made — actively recorded, automatically recorded, typed in by a person — and the data-confidence card was checking that label against the wrong value. It warned you about manual entries whenever your watch had recorded the night properly, and a night you genuinely did type in was never counted at all.
The hydration goal bar filled up if you logged a single day. It measured the average of the days you logged against your goal — so a week in which you logged Monday, hit your target and never opened the app again showed a completely full bar, with “1 of 1 days met” above it. Log nothing and you cannot fall short of anything. It now counts the days you met your goal against the days that have actually happened, and stops at today.
A day’s heart rate could print an average outside its own low and high. The average came from Health Connect’s summary of the day while the low and the high came from the individual readings — two different sets of numbers printed as one. All three now come from the readings.
The skin-temperature card went blank while its own chart carried on drawing. A reading that arrives without a temperature difference emptied the card while the chart underneath it plotted the readings that had one.
Respiratory rate showed two different averages on one screen, and said neither which was which: the average of your days under the chart, the average of every reading on the card below it.
An Apple Health import that failed on permissions offered no way to fix it. The “grant permission” button could never appear, because a permission failure was never reported as one.
Screens could spin forever after a failed permission check — on the dashboard, in onboarding, and while saving an activity, the error was thrown where nothing was listening.
The app was rebuilt on Flutter’s app-architecture guidelines. Every screen now works out what to show once, when its data loads, rather than recalculating charts, totals and statistics on every redraw while you scroll. It is invisible if it went well, which is the point — and it is the groundwork for iOS.

2.0.3 - 2026-07-12

An activity could show no heart rate at all, and its splits fell back to estimates. Health Connect stores heart rate, speed and cadence as series records — one record holding many timestamped samples — and filters them by the boundary of the record, never by the times of the samples inside it. A device may group a whole day of beats into a single record, and a 36-minute workout sitting inside one was therefore invisible: the read succeeded and returned nothing, so the activity reported “Not available” for a heart rate it had recorded the entire time. The same read backs the speed samples, so the 1 km splits quietly dropped to being estimated from the average on exactly the same activities.
The sleep graphs were blank. The night’s stage timeline and the “share of time in bed” bars drew their coloured bands with zero height — beside durations and percentages that were correct all along.
The weekly activities view lost the strip showing which days you trained. It is back.
Beverages logged from a home-screen widget were silently dropped. The release build strips code it cannot see being used, and the widget’s buttons are found by reflection at the moment you tap them — so the tap did nothing and the drink was never recorded.
A strength session was cut into distance splits. A phone left on a bench picks up a couple of hundred metres of GPS drift, and a lifting session was sliced into “1.0 km” and “181 m” laps at a 30:29 min/km pace. Whether an activity has splits is now a question about the kind of activity, not about whether a distance happens to exist for it.
Focus mode now fills the screen. It was rendering under an app bar whose Back arrow did exactly what focus mode’s own exit button — and the system back gesture — already do. The height it was taking now goes to the metrics.

2.0.2 - 2026-07-12

A walk or run recorded by a watch now shows its steps, distance, calories and elevation. A watch writes an activity as a session carrying little more than a duration, and puts those numbers in separate Health Connect records covering the same window — so the activity’s page reported “Not available” for figures the watch had in fact recorded, directly above a chart of that same activity’s step cadence and splits that added up to a distance the page refused to show. A device that records speed but no distance at all, such as a treadmill, now gets a distance derived from its speed, by the same arithmetic the splits already used.
Speed and cadence recorded on a ride or run are charted again, and the metrics list no longer advertises figures the activity was never going to have — “Wheelchair pushes” and “Floors climbed” on a bike ride, permanently “Not available”. A metric now appears when it has a value, or when its absence is worth reporting for that kind of activity; a value that was actually recorded is never hidden.
Fix the large empty gap above and below the recording dashboard, which in outdoor mode’s black background read as a broken screen.
Fix the crash when importing an offline map pack or a large Apple Health export. The file picker read the whole file into memory before the import began, so a 205 MB pack ran out of memory before any import code ran.
Fix adding a home-screen widget: the metric widget opened the beverage picker (and vice versa), the picker could crash after a selection, and the widget was sometimes never created at all.

2.0.1 - 2026-07-11

Your Health Connect data is not affected by this update. Health Connect stores it outside OpenVitals, so the rewrite cannot touch it: steps, sleep, workouts, heart rate, hydration, and every other record stay exactly as they are.
Two app settings reset: the dashboard tile order, and the beverage picked in the quick-beverage home-screen widget. Set them again after updating. A one-time migration carries the rest across automatically — goals, units, theme, the caffeine profile, the body and heart-rate profile, reminders, custom drinks, paired Bluetooth LE sensors, activity marker notes, offline map packs, and your logged beverages.
Rebuild OpenVitals on Flutter. Same app, same features, same Health Connect data — and the foundation for an iOS version later. The package name and signing certificate are unchanged, so it installs as a normal update.
Activity splits. Any activity with a distance is broken into segments — 1 km by default, configurable in Settings — showing pace, average heart rate, elevation, and how each segment compares to the activity’s own average. Laps recorded by a watch are shown exactly as recorded; an activity with no per-time distance data is split evenly and labelled as an estimate rather than presented as a measurement.
Make Apple Health imports much faster on large exports by skipping records in categories you did not select, and show real progress while the export is scanned instead of sitting at 0%.
Fix missing heart rate at the start of a recorded activity.
Fix the dashboard showing the default daily goals instead of yours, the beverage breakdown showing the app’s package name instead of drink names, the missing beverage list in the Day view, and the metric carousel refusing to swipe after a tile was moved between pages.
Share sanitized diagnostics logs directly from Settings.
Reminders may now arrive a few minutes later than the time you set. Google restricts exact alarms to alarm-clock and calendar apps, so hydration and mindfulness reminders are delivered within a short window instead of on the dot.
