My Revive Cycle Alarm didnt go off and I did not set a back up alarm. Luckily I didnt have to be anywhere that morning. However, if I paid $5 for an app, 100% of it should work. There are free apps out there in general that are more reliable. This app was feature on PBS Spacetime. Dont let their promotion of you go to waste.
