Thrise vs Alarm Clock Xtreme — loud alarm showdown
Both promise you can't sleep through them. Here's how Thrise and Alarm Clock Xtreme compare on loudness, dismissal, privacy and platform.
2 min read
Short answer: Both Thrise and Alarm Clock Xtreme are loud alarms aimed at heavy sleepers, and both make you do something to switch the alarm off. Alarm Clock Xtreme is a long-standing, feature-packed clock (mainly on Android) that dismisses with math or shaking; Thrise is an iPhone-native app that verifies real movement on-device — camera-counted exercise — with a gentle sunrise, offline no-account privacy, and design. Choose Thrise if you’re on iPhone and want a movement-based, private wake-up; choose Alarm Clock Xtreme if you want a mature, configurable clock on Android.

Where Thrise stands out
- Movement, not just math. Thrise dismisses with real exercise (camera-counted push-ups) or getting on your feet — physically harder to fake than a math puzzle you can solve half-asleep.
- Gentle sunrise + loud alarm. It surfaces you with light and then rings loudly, rather than only blasting a tone.
- Offline and private. No account, nothing uploaded, camera missions processed on-device. Swiss-made.
- iPhone-native. System-level wake-up that rings through Silent mode and Focus.
Where Alarm Clock Xtreme stands out
- Android and maturity. A long track record and deep configurability, and it’s available on Android where Thrise isn’t.
- Classic dismissal tasks. Math, shake, and barcode-scan options.
- Free tier. Ad-supported free use.
Who should pick which
- Pick Thrise if you’re on iPhone and want a loud, private, movement-based wake-up with a gentle sunrise.
- Pick Alarm Clock Xtreme if you’re on Android or want a highly configurable classic alarm with a free tier.
