8 of 25If you search for Atomic Clock on the App Store, everything you find but this is mostly junk. iOS 26 update: YEP! Still the best! With configurable NTP server, cross platform support, and perfect synchronicity; it’s worth every dime.
Does exactly what an atomic clock should do. Since I can’t call time anymore, this is the next best thing.
Stopped being woken up by this alarm a while ago, just sat down and set it to the next minute, and it still didn’t go off. Waste of money, un functioning app. Fire your software developer.
App is always there to set my watch by, couldn’t ask for more.
One of OG Apps here in the Apple AppStore and it’s still the best. I’ll be making a donation! I hope this app never goes away!
When are you going to update your software?
My go to app for atomic time. I use it for setting my watches and have done so for years.
One of my top three favorite atomic clock apps!!!
