User Reviews

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.

Tired of worrying about whether or not my alarms will ever go off. And in the latest set of issues, changed the time for my alarm and it still went off at the original time. This app has burnt me too many times.
