What's the best iOS app for waking up even if you're a heavy sleeper?

If you're the type of person who can sleep through anything, Alarmy: Loud Alarm Clock, Sleep might be exactly what you need. It's not just about loud noises; it's about making sure you're actually awake and alert. Alarmy forces you to complete missions like solving math problems, scanning a barcode, or even taking a photo of a specific object in your house before the alarm will shut off. This means you have to physically and mentally engage, making it much harder to fall back asleep. The app also offers a variety of alarm sounds, from gentle melodies to truly obnoxious noises, so you can find what works best (or worst!) for you. For heavy sleepers who've tried everything else, Alarmy's mission-based approach can be a game-changer.
