Comments on Atomic Clock & Watch Accuracy for Android

★★★★★ Francesco Memet · Jan 11, 2026

Excellent. I have a watch which has an accuracy of +/- 1 second every 100000 years. Linked to an atomic clock. It's good to check it, every now and then to see its keeping in sync. And this is just the app to use.

★★★★★ Jonathan Graham · Oct 13, 2025

The best app I've found for tracking watch accuracy over time. Simple to use, and doesn't require you to wait for the top of the minute like other apps.

★★★★★ Mark D · Apr 27, 2026

I regularly use this to set mechanical watches. The countdown sound is very helpful

★★☆☆☆ Ian Gourlay · Dec 11, 2025

I bought a copy of this fairly useful app, yet its current version after a few seconds of being launched, obscures the lower half of the screen with adverts. I suggest that you avoid its use, as the writer is clearly motivated to ransom its access and usability to repeat cash demands to restore app usability. There are other apps for monitoring watch accuracy (including an excellent simple telegrapher) and those have my recommendation over this one, now being uninstalled in disgust.

★☆☆☆☆ Nicholas Seale · Nov 8, 2025

Ad filled the screen and covered a settings button. Can't set custom ntp servers

★☆☆☆☆ ABJ photography & video · Nov 19, 2025

Not even tried this data grabber app. Instead of accept all there should be an option to deny all
