- Email verification if account is not verified
- Home dashboard if authenticated and verified
- Home dashboard provides:
- Tasks
- Profile
- Leaderboard
- Settings
- Notifications are initialized during app startup.
- Reminder scheduling is timezone-aware.
- A task reminder is scheduled only if:
- the global notification toggle is enabled
- the task has a valid future reminder
- the task is not completed
- Completing or deleting a task cancels its scheduled notifications.
Battery optimization can delay or suppress notifications on some Android devices.
The app now includes a Battery Optimization entry in Settings:
- it reads the current optimization exemption status
- it opens the Android system battery optimization screen
- it helps the user whitelist the app for better notification reliability
Important:
- this setting cannot be silently changed by Flutter alone
- Android requires the user to confirm the change in system UI
- Flutter SDK
- Firebase project configured for Android/iOS

- Android 13+ requires notification permission.
- Some Android versions/devices also require exact alarm approval for precise scheduling.
- Even with exact scheduling, aggressive OEM battery optimization may still delay alerts.
- The app provides a battery optimization settings shortcut, but the final permission change is system-controlled.
- The repository still contains a default sample widget test that does not reflect the real app bootstrap and will fail without Firebase-aware test setup.
