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.

99% of the time this app only show’s advertisement. When you can “finally” exit the advertisement, here comes the next advertisement. Worthless as a clock.
