Yep can do other things on your phone while the alarm is ringing, just don't remove it from your background. Even though we recommend you to lock the phone with the app open.
How? Do not swipe the app off from the multi-tasking screen Screen shown when you swipe up from the bottom to the top of your screen. If possible, it's best to swipe off other apps than Alarmify.
- Have in mind
Only when Alarmify is terminated in the background which means closed from the multi-tasking screen, alarm can't ring.
