I did have an app on my iPhone that would sync with servers to get the precise time. When I got my new iPhone that little app was no longer available so I looked for an app that would give me precise time. Atomic Clock does just that and the one time charge was around $6.00 I believe.

No possibly to say no to all vendors. The list was soo long I have rather uninstalled it than going through all of them.

Fine app, it shows, to 1/100 of a second, the Time per the Internet Network Time Protocol, or NTP. The NTP is coordinated from hundreds of atomic clocks around the world. Everything now runs off NTP: TV, radio, satellites, GPS, air and seaborne navigation, fiber optic communications, everything.

The app is really good, except trying to pay for the pro version will not allow me to use what is in my account. Always wants to go to the primary of my family account.

I use this app for astronomy, and also for setting and checking my watches. Easy to use, with many features.

Thank you - this is a great app for calibrating and tuning mechanical clocks against.

Une honte, un harcèlement incessant de pubs qui vous cache l'essentiel de ce qui vous intéresse, à savoir le cadran. J'efface immédiatement.

La publicité est gênante dans la version gratuite. Je viens de passer en version « pro » et l’application est vraiment plus agréable à utiliser 👍

App has become unusable. Ads cover entire page blocking view of atomic time. There is also no “X” to close out the ads.
