Sleep better and start the day with your favorite tunes. Are you curious to see how much you slept? Then, track your sleep in the app. Alarm Clock HD is the app to help you enjoy restful sleep and wake up worry-free. How Alarm Clock HD helps you sleep better: • Unlimited Alarms: Apple Music or Alarm Sounds • Customize Nightstand display colors • Sleep Timer • Local Weather Information • Instant Flashlight - shake the device • Full watchOS 2 support • Screen Saver - for devices with OLED display WAKE UP ON TIME: Proper Alarm Settings • Keep the app open and running always to have your alarm go off and play the sounds you’ve set for ‘Music'. When your app is open, you can use the volume slider within the app. When the app is in the background, use the device volume to set your volume. • Make sure your battery is charged and have your notifications turned on before you go to sleep, when the battery level goes below 30% it might not sound. This is due to prevent the device from dying and the alarm not going off. • Keep your Apple Music available on your device The music you can select consists of everything you have available on your ‘Apple Music' app on your device. If the music is saved on your iCloud, and not on the device itself, it won’t be available. NEVER MISS AN ALARM When you close the app and do not have it running in the background, the alarm will use the device volume instead and play the notification sound system. The app will close itself automatically after 10 hours of inactivity. This is due to prevent the device from dying and the alarm not going off. When your device is muted, set to ‘Do Not Disturb’, or your device volume is set to 0, the alarm won’t play properly. It will still show the notification without any sound. This is due to Apple’s restrictions as we are unable to access the app settings when the app is closed, only when it’s open or running in the background.

Verdict
The clearest difference is price: Alarm Clock HD at Free against Simple Date Wheel's $0.99. Alarm Clock HD also leads on ratings volume (104K vs 11). Simple Date Wheel's advantage is review sentiment (73% vs 32%) and in-app purchases (none vs 11). On rating, update cadence and device support there is nothing between them.

Alarm Clock HD is free to download; Simple Date Wheel costs $0.99 up front. Alarm Clock HD sells 11 in-app purchases, starting at $1.49 per month. Simple Date Wheel asks for nothing beyond the download.
Alarm Clock HD holds the better App Store score, 4.5 against 4.4. That said, the two scores are not equally well evidenced: Alarm Clock HD has 104K ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 32% of Alarm Clock HD's written reviews are positive against 73% of Simple Date Wheel's, so the app with the better star average is not the one people write more warmly about.
Alarm Clock HD ships an update fortnightly, Simple Date Wheel every 8 days. The most recent releases landed on October 31, 2026 and October 24, 2026 respectively.
