There seems to be no wake up for Fajr option. You have to set a specific time of day to be woken up. Also, you have to select each day, and you can only select everyone of those days. So I cannot just select "Everyday", and I cannot say just tomorrow at 3:30 AM. The contact form does not seem to work correctly on iPad Air. Everything is garbled at the top and it will not let you type or select anything.
