I built Rutin while managing my own TB treatment. Taking medicine at exact times, every day, for 6+ months — a missed dose isn't just a bad habit, it can cause drug resistance. Every existing app I tried was either too generic, paywalled, or unreliable when it mattered most.
So I built the one I needed. Then I kept going, because the same problem applies to anyone trying to build consistent health habits.
Alarm-grade. Re-notifies every minute until confirmed taken. Full-screen takeover persistent even if the notification is dismissed. Supports multiple daily doses, food timing (before/after/with meals), snooze, and a monthly adherence calendar. Alarms survive reboots via RECEIVE_BOOT_COMPLETED.
Interval-based reminders within a configurable active window. Quick add/remove glass, WHO-based daily target, inline undo, and a live countdown to the next reminder.
Multiple reminder times per habit. Per-reminder completion tracking. Streak tracking with partial-day survival — missing one reminder doesn't break a streak, missing the whole day does. Habit stacking: chain habits into routines with a shared stack streak. Calendar history per habit.
A native Android foreground service detects sleep passively via screen-off timing. On unlock, a morning dashboard appears before the phone is usable — showing today's medicine and habits, then a randomly rotating wake-up game (Sequence Memory, Tap Rhythm, or Connect the Colors). An AccessibilityService prevents skipping the gate via the Home button.
Track long-term treatment schedules — TB, Typhoid (Tifus), Malaria, ARV, chemotherapy, or any multi-week/multi-month medicine program. Day counter, adherence score, and PDF export via printing package.
Three auto-calculated personal records: Water Intake, Medicine Streak, Habit Streak. PR-only tracking — never resets on a streak break. Tappable medal cards with a detail sheet.
Alarm-grade notifications — NativeReminderScheduler.kt uses AlarmManager.setExactAndAllowWhileIdle with sound-keyed notification channels. Channels are recreated on sound change (Android channels are immutable after first creation). Reminders re-arm automatically for the next day.
Sleep detection without sensors — SleepModeService sets sleep_active on screen-off after 10 minutes of silence. Notification wakes (keyguard still locked) don't reset the timer — only actual user unlock does. Audio/video grace period: if playback is active, polls every 5 min via AlarmManager. Works on Android 13+ with the FOREGROUND_SERVICE_SPECIAL_USE type.
Home button intercept — RutinAccessibilityService keeps the morning gate on screen even if the user presses Home or switches apps, without blocking emergency calls or system UI.
Sound-keyed notification channels — each notification sound gets its own channel ID (e.g. habit_reminder_chime). Separate sound settings for medicine vs. habit alarms. Changing a sound deletes the old channel and creates a fresh one automatically.
No build_runner — Hive adapters are hand-written. Keeps the build fast and removes a fragile codegen step.
Offline-first, always — all data lives in Hive on-device. Sensitive boxes (medicines, medicine_logs, tb_profiles) are encrypted with HiveAesCipher + flutter_secure_storage. Firebase Analytics is the only network call, with no PII in event params.
