The Alarmy app is known by many to be the "world’s most annoying alarm clock," and for good reason. This annoying app lets you set alarms that will go off just let any other alarm clock.

Loud Alarm Clock is free to try and use, but you can pay a one-off fee of $8 to remove the ads and get more sound options. The app is only available for iOS.

The alarm clock app, Nuj, is guaranteed to get you out of bed on time. If you don’t, you’ll have to pay up in real money. It’s wake up, get up, or pay up.
