Android app for regular movement breaks at the office. Set a timer, start it, and get a random exercise when it expires. After confirming, the timer restarts automatically -- endlessly, until you manually reset.
- Adjustable timer duration (hours + minutes) via sliders or manual input
- Configurable repetition range (min/max) with linkable sliders for fixed or randomized reps
- Circular countdown display
- Shuffle-bag exercise selection -- cycles through all enabled exercises before repeating, persisted across app restarts
- Auto-restart after exercise confirmation (configurable -- can be disabled)
- Foreground service with persistent notification (stays visible until manual reset)
- Audible beep alert on timer expiry with configurable beep count (1-5) and custom notification sound support
- Vibration alert on timer expiry
- Lock screen notification with screen wake-up on timer expiry
- TTS break announcements -- exercise names read aloud via text-to-speech (localized)
- Work schedule -- per-day start/end times, break pause with auto-pause/resume, time inheritance via link icon, weekend/off-day detection, night shift support
- Per-day exercise mode -- optional master toggle binds a default mode (Workout / Mobility / Office) to each weekday, link-inherited from the first unlinked day; today's mode is applied automatically on app foreground, onboarding finish, schedule edits, and toggle-on
- One-day mode override -- manually picking a mode in the exercise settings stores a transient override for today only (persisted across backgrounding and process death); cleared automatically on timer Stop, end-of-shift, or day rollover; never modifies the weekly plan
- End-of-shift screen -- friendly "Schönen Feierabend" / "Enjoy your time off" notification when work hours end, so the timer stop is never a surprise
- Break pause screen -- "Schöne Pause" / "Enjoy your break" screen during scheduled breaks with auto-resume info
- Freestyle mode -- automatically detected when starting outside work hours; disables auto-stop and break pausing so the timer runs freely for after-work use
- Custom notification sounds -- pick audio files via SAF, preview before saving, reset to default
- Persistent volume bar at top of timer screen
- Home screen widget (Glance) -- today's break count, current streak, live second-by-second timer countdown with paused/expired/idle states, and a Start button that launches a break directly from the home screen
- Exercise context modes -- three switchable presets (Home Office Workout, Home Office Mobility, Office) with instant mode switching via segmented button; 25 built-in exercises across all modes
- Exercise management (add, remove, enable/disable per mode)
- Achievements system with unlockable milestones and share-to-social (image card via share sheet)
- Stats tracking -- weekly reps, week-over-week comparison, most frequent exercise (all data stored locally)
- Fitness levels with progression
- Dynamic difficulty increase with adaptive threshold (optional)
- Data export and import via JSON backup (SAF integration)
- Imprint and Privacy policy links in Settings
- Google Play build only -- toggle in Settings to disable Android Auto Backup to Google Drive
- Onboarding flow for first-time users
- Theme switcher (System, Light, Dark)
- Language switcher (German, English, System)
- Keep screen on during countdown (optional)
- Material 3 theming

./gradlew assembleFdroidDebug # explicit F-Droid build
./gradlew assembleGplayDebug # Google Play buildThe app has two product flavors:
fdroid(default) — Android Auto Backup disabled, fully privacy-strict.gplay— Android Auto Backup enabled (settings sync to Google Drive); user-toggleable from Settings.
Both flavors share the same applicationId (de.mysportsmate.officebreak).
./gradlew assembleFdroidRelease # signed APK for F-Droid / GitHub Releases
./gradlew bundleGplayRelease # signed AAB for Google PlaySigned release builds require a keystore.properties file in the repo root (git-ignored).
./gradlew test # all flavors
./gradlew testFdroidDebugUnitTest # fdroid only
./gradlew testGplayDebugUnitTest # gplay only./gradlew lint # default variant (fdroid)

Available via Google Play (gplay flavor with Android Auto Backup enabled).
Pre-built signed APKs are attached to each release.
