Thank you guys for testing the app. @albloushi: Translation to arabic is on my to-do list , hopefully will get around to doing that soon. @fuzzbuzz: prayer times are calculated using some complex equations.. you can find more info here -> http://www.tanzil.info/praytime/doc/calculation/ @new_bee: I had the same problem. You can find configs under /home/user/.config/Team Mohannad/PrayerTime.conf For now if you need to make changes you can edit that file, I plan to have an 'options' window in my next release.
