In closed testing on Google Play
An offline prayer times, adhan and Qibla app for Android, in English and Arabic. No accounts, no ads, no analytics and no prayer-time API.

Android compasses report magnetic north, but the Qibla bearing is measured from true north. The gap is about 4.8° in Cairo and 12.5° in New York, enough to point someone the wrong way.
I implemented the World Magnetic Model (WMM2025) in Dart to add the local declination, and tested it against all 100 of NOAA's official test values. iOS already reports true north, so every compass reading carries which north it uses and is never corrected twice.
The adhan plays on Android's alarm stream, so it's heard even with notification volume low, and scheduled alarms are restored after a reboot or app update.
For people who rarely open the app, a daily WorkManager task tops up the schedule in a headless isolate. It reuses the app's own scheduler instead of a second copy, and never asks for location or the network in the background.
Every layout uses directional widgets and every string and number is localized, including Arabic-Indic numerals and Hijri dates.
A text-scale matrix of 320 tests renders every screen at 1.0× to 2.0× text, in both languages, on five screen sizes, and fails on overflow, clipped text or words broken mid-word.
Feature-first clean architecture: each feature has its own data, domain and presentation layers. State lives in Cubits, dependencies are wired with get_it and routing uses go_router.
I'm open to junior Flutter and mobile developer roles and internships. If you're hiring or want to talk about an app, my inbox is open.
