User Reviews

Overall, Twelve O'clock is a low-cost, user-friendly tool for horology enthusiasts to track watch accuracy over time. Users appreciate the simple interface, ability to log multiple watches, and useful charts/history that reveal how positioning and wear affect performance. The $0.99 full unlock offers good value for those tracking several watches. However, reviewers note notable downsides: a restrictive free tier (limited checkpoints and single watch) and occasional data loss or app hangs after updates. Despite these issues, it remains a strong, specialty tool for dedicated hobbyists.
Pros
  • Very affordable one-time purchase unlocking full features.
  • Simple, intuitive interface that makes tracking easy.
  • Accurate real-world watch accuracy data with helpful charts/history.
  • Supports tracking multiple watches and sorting by accuracy.
  • No ads in the free version (pleasant free experience).
Cons
  • Free version limits: only five checkpoints and one wristwatch; upgrade required for more.
  • Data loss/hangs after updates; several users reported losing all entries or the app freezing.

Great for tracking mechanical watch accuracy and only a dollar to access all the features. Only suggestion for quality of life is the beeping sound mechanic for the 57, 58, 59, and 60 sec. It only works/ makes sound if the iPhone is not in silent mode (bell icon off).

Simple. Does exactly what it claims, and makes it easy. One thing I do wish it had is notifications/reminders

This is a must for automatic movement enthusiasts. Very easy to use, the watch article compilation is a nice touch as well. Full app for only .99 one time purchase.
