Simple Alarm is the alarm that finally shows what the built-in Clock hides: exactly how long until it rings. Set an alarm and instantly see "in 4h 33m" — on the list, on your Lock Screen, and in a beautiful full-screen countdown. No more guessing how much sleep you'll get tonight. Built on Apple's AlarmKit, so it rings reliably — even in Silent mode and Focus, even if you force-quit the app or restart your phone. It looks and behaves like the native alarm, just with the countdown you always wanted. FEATURES • Countdown to every alarm — see how soon it rings, everywhere • Reliable ringing through Silent mode & Focus • One-time and repeating alarms, snooze, custom sounds • Power naps — 5 to 90 minutes, one tap • Statistics — track wake-ups, snoozes and naps • Pleasant built-in sounds, or import your own • Light & dark, and your language • Private by design — no accounts, no tracking, no data collected Requires iOS 26.

Verdict
The clearest difference is ads: Simple Alarm at none against Battery Coach's shown. Battery Coach's advantage is iOS requirement (17.0 vs 26.0). On price, in-app purchases and device support there is nothing between them.
