Super Alarm
Alarms you can't sleep through — scan a QR code to dismiss
iOS 
SwiftUI 
Kotlin Jetpack Compose Super Alarm exists for people who dismiss alarms in their sleep. The only way to silence it is to scan a QR code — stick it in the bathroom and you’re up. If the app is killed or the phone is silenced, backup ringing and iOS Critical Alerts still get through.
Both apps are native — SwiftUI on iOS, Jetpack Compose on Android — with built-in diagnostics that verify your alarm will actually fire. The Android app ships on Google Play; the iOS release is still pending.
