FAQ

Frequently Asked Questions

YouTube videos, playlists, channel uploads, and Shorts; Apple Music tracks; imported audio files; and voice recordings. Shuffle playback is also supported.

Yes. Use the sleep timer to fall asleep to music, the multi-timer for cooking, studying, or naps, and the stopwatch with lap and split support.

Incoming calls, Low Power Mode, or Screen Time restrictions may interfere in rare cases. Silent mode is overridden, streaming failures fall back to a local backup track, and AlarmKit Assist (iOS 26+) adds a system-level safety net.

No — iPhone alone is sufficient. The accelerometer tracks Awake, REM, Core, and Deep sleep stages automatically. An Apple Watch unlocks the heart-rate-based Smart Alarm on top of that.

All core features — alarms, sleep tracking, timers, and wake-up challenges — are free. Premium ($0.99/month) adds ad removal, weather forecasts, auto-stop alarms, and Lock Screen dismissal.
