Make sure you run the app at least once a week. Prayer time changes every day based on the position of the sun. We can therefore not set a recurring alarm (which would go off everyday at the same time) and need to set each Adhan separately for everyday.
Pre-programming notifications in advance uses time, memory and battery. We therefore decided to program, every time you run the app, Adhan notifications for the next 10 days. If you run the app at least once a week, this is transparent to you.
Run the app at least once a week
If you have not run the app for 9 days, you should receive a notification to launch it. So if the Adhan notification has stopped working for you, just launch the app and the issue should be fixed.
Please note that if you have recently updated your device to iOS 5.x, you may need to re-enable notifications for the Muslim Pro application from the Notifications menu of your device’s Settings screen.
