Mashallah, this app does exactly what it says! I am a person who sadly have missed a lot of fajr prayers, for lots of reasons, but mainly I am a heavy sleeper. I love this app because it is impossible to just snooze! I use the shake option and its been working great so far. If u need help waking up, get this app!
جزاكم الله الف خير!!!
