AtomicClock: NTP Time

Really want to say thanks to the developers for great authentic customizable app. The app, that do it’s job 100% and not bothering in free version too. Great functionality. Greenwich signal. Etc... Etc... Paying myself fair amount to the devs with a free of a will, because the app is great and handy, comparing to many other. Let it be just like that all the time! It’s perfect! PS We (watch holders) do not have a choice to have an app to calibrate the clock movement, at the moment, for a reasonable price on IOS. The precision of that kind of apps may be not enough to calibrate the quartz movement, but it can be done too. The apps, that hearing the clock beat with an internal/headset mics are cost much more, than it may be. It will be great to see one from your team. I’m sure it will be a second “must have” app for watch care. Good luck!

Excellent app... would recommend it to my friends.

This app does exactly as one would expect AND it’s appearance is extensively customizable. About the only thing missing is a version for the Apple Watch…hint, hint!

I’m impressed with the way the clock works. Right down to the second. Great app.

And it works perfectly! Thanks dev. I appreciate it.

I first started using this app in December of 2021 and use it multiple times a day on a daily basis. It helps to accurately set my timepieces and synchronize many gadgets that I work on. It’s great that you are able to set the clock face as simple or complex as you want, with an endless array of display and face settings. Thank you for making such a great app that’s easy to use and allows so many user options. All of the updates have been positive improvements - not that it’s lacking to begin with. This is how apps should be made.

It’s a great app specially if you need to synchronize regular clocks. If you turn ticking on. The last five seconds before the top of the minute the ticking tone changes and at the top of the minute it changes to a very distinctive tone. Hundreds of years ago sailors needed extremely accurate measurements of time to get a precision indication of their position. A clock just a full minute off would have them miles off their true position. Not the best of news when you have reefs and shoals anywhere nearby. Remember all the old WWII movies? Just before they went on the offensive the commander had everybody synchronizing their watches. Same with this app. You can get a idea of just how accurate your time pieces really are. Synchronize a time piece with it and compare it a week later. Is it running fast or slow? You can get a general idea of what your time pieces are doing when you’re without the internet. You can learn to leave for a time sensitive location like a bank or your job earlier for time pieces tending to run slow.

Very good. Time is accurate. Adjusting settings is straightforward.
