The problem
Many prayer apps need an account, show ads or send location data to a server. We wanted one that calculates everything on the phone, works without internet and respects the user's language, including right-to-left layouts.
What we built
Version 4.0 is a ground-up rewrite in Kotlin and Jetpack Compose. Prayer times are calculated on the device, reminders use exact alarms that survive restarts and time-zone changes, and the app requests no internet permission at all.
Key features
- Prayer times calculated on the device, with 10 calculation methods, Hanafi or standard Asr, and high-latitude rules
- Exact-alarm prayer reminders that are set again after a restart, update or time-zone change
- Qibla compass corrected to true north, with calibration help and a fallback for phones without a compass
- Digital tasbeeh with custom dhikr, targets, haptics and a daily total
- Zakat calculator with gold or silver nisab; figures are never saved
- Hijri date with a manual adjustment of up to two days
- English, Urdu and Arabic with full right-to-left layouts, light and dark themes, phone and tablet layouts
- No accounts, no ads, no analytics and no internet permission

Challenges and how we handled them
Accurate times with no server
All calculations run on the device. Unit tests compare the results against published timetables for different methods and locations.
Reminders that do not go missing
Android can clear scheduled alarms after a restart or update. The app listens for those events and sets every reminder again.
