## Description

Alarm Clock HD helps you wake up reliably with unlimited alarms using Apple Music or built-in sounds. It also offers sleep tracking, a sleep timer, local weather, customizable nightstand colors, a flashlight shake, full watchOS 2 support, and an OLED-friendly screen saver.

Premium Membership unlocks ad-free use, extra feeds, and premium support. For reliability, keep the app open or in the background, ensure your device battery is charged, and enable notifications; if the device is muted or in Do Not Disturb, alarms may not sound. The app can close after 10 hours of inactivity and the music source must be available on-device via Apple Music.

## Review summary

Reviewers largely praise Alarm Clock HD's long history and basic alarm features, with some noting it was a great, simple clock in years past and enjoying the crystal drops sound. However, the dominant sentiment is negative due to intrusive ads, a costly subscription, and critical reliability issues (alarms failing to go off, going off late, or snooze/stop not appearing). Additional frustrations include ad-driven UI interruptions, DST/time changes breaking alarms, and compatibility problems on newer devices. A minority still values its familiarity and core functionality despite these problems.

### Pros

- Historically reliable alarm clock with years of user adoption.
- Simple, straightforward alarm setup and core features.
- Pleasant alarm sound option, notably the crystal drops sound.
- Some users still view it as a great alarm clock despite recent changes.
- Past positive sentiment on reliability and simplicity before ads and updates degraded.

### Cons

- Intrusive and persistent ads that block usage and require long waits.
- Expensive subscription model / annual fee; perceived as outweighing a useful free version.
- Alarm reliability problems (not sounding, going off late, or failing to respond to snooze/stop).
- UI/UX issues caused by ads (buttons not visible, ad popups interfering with setup).
- Daylight Savings/time-change issues and device compatibility problems with newer iPhones.
