Prayer times look a few minutes different from my mosque
The app uses the Shia Ithna Ashari (Jafari, Leva Institute Qum) method: Fajr 16°, Maghrib 4°, Isha 14°. Local mosques sometimes add their own precautionary minutes. Make sure your location is correct on the Prayer screen (tap Change → Use my current location).
I don't get azan alerts
Open Prayer → Turn on alerts and allow notifications. Check that the bell is on for each prayer, that Sound is on, and that notifications for Quran & Duas are allowed in your phone's Settings. Open the app at least once every week or so; it schedules the next 12 days of alerts each time.
The Qibla compass isn't moving or seems off
Hold the phone flat, away from magnets, metal and magnetic cases, and move it in a figure-8 to calibrate. Allow location for the most accurate direction (true north).
The Islamic date is one day off
Months begin with the local moon sighting. Open the calendar (Today → Full calendar) and use the moon-sighting adjustment (−1 / +1) to match your community.
Recitation won't play
Recitation streams over the internet, so check your connection. Everything else in the app works offline.
