Multiple Alarms with Three Simple Steps: By selecting a start time, end time, and notification interval, then tapping the alarm button, you can set alarms at specified intervals for the designated time period. Easily Register Favorites: Once you've set an alarm, just tap the “Add to Favorites” button. After that, you can load that alarm anytime with a single tap. Simple Design: It’s easy to use because there are no unnecessary features besides the alarm! Works in Sleep Mode for Your Peace of Mind: The alarm continues to ring only when your device is in sleep mode or on the lock screen, so it won’t bother you once you’re already awake. Important Note: Because this app uses notifications for alarms, if your device is in silent mode or set to vibrate only (where notification sounds are turned off), the alarm will not sound.

Verdict
The clearest difference is in-app purchases: Sleepyhead Alarm at none against FadeInAlarm's 1. Sleepyhead Alarm also leads on update cadence (every 3 months vs every 7 months). FadeInAlarm's advantage is ads (none vs shown) and iOS requirement (16.0 vs 18.1). On price and device support there is nothing between them.
