Comments on Atomic Time - NTP Clock Sync for Android

★★★★★ Dave · Feb 11, 2026
Perfect for re-syncing watches & clocks. No Ads, no feature locked behind paywall, option to sync to NIST, audible tick option makes it easy to check watch sync, and it only takes up about 18 mb
★★★★★ Keith · Jul 12, 2026
Great app for setting the correct time on your analog clock
★★★★★ Andres Lobo · Jun 23, 2026
Simple and elegant. Thanks for making this App. Perfect for syncing my watches and clocks to atomic accurate time :)
★★☆☆☆ Емилиян Николов · Aug 5, 2026
Lies that it syncs to the custom server. I wanted to use it to diagnose a custom NTP server, but it doesn't seem to sync with it at all. Instead, it takes time from whatever public server it decides and insists it is the time from the custom server.
