Comments on Atomic Clock & Watch Accuracy for Android

★★★★★ Tony Vienonen · Jun 27, 2026

Beep, beep, beep, beeeeep. On time, every time. This is great for setting those clocks that run fast or slow

★★★★★ 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.

★★★★★ Keith S · Apr 29, 2026

Excellent tool. I use it every morning to reference the time on my automatic watches. If you have a mechanical watch then this is for you

★☆☆☆☆ Stuart Harrell · May 20, 2026

This app turns into an ad when minimized, making it useless. It doesn't even deserve one star.

★★☆☆☆ 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.

★☆☆☆☆ 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
