Comments on AtomicClock: Exact NTP Time for Android

★★★★★ William Hoffman · Nov 19, 2025

Excellent time keeping App!! Definitely the best Clock app I've ever had in 25+ years. Highly recommended! I set all my watches and clocks around my house and at work with this app. Hasn't let me down yet. Great buy. Thanks a million! Will H. 👍🙂🇺🇸❤️

★★★★☆ Kenagain · Oct 31, 2025

Had the free version for a long time and decided to get the paid for version. Found that the paid for one says you can change fonts and font colors, but they don't work as they should. I tried changing the color to red, and it stayed white but changed the font on the widget. If it gets sorted will give it 5 stars.

★★★★★ Rupert Reynolds · Jan 18, 2026

Does exactly what it should--displays *accurate* time from the atomic time standard. Worth paying for, so I did :-)

★☆☆☆☆ Karl Stevens · Jan 2, 2026

I was unable to use it because of the obtrusive ads. Having a popup that takes up the entire screen makes this useless.

★★☆☆☆ James Brown · Jan 4, 2026

The clock gets covered by ads, so it's useless.

★☆☆☆☆ Lawrence Widacki · Sep 20, 2025

I uninstalled the app because of the ads now. This app used to be ad free.

★★☆☆☆ Andy Brownfield · Dec 28, 2025

The app is clean and works well, but the ads pop up and cover most of the clock. It's annoying to use, so I'm installing a different atomic clock app.
