This has been my go to app for ensuring all my personal and home devices have the accurate time settings. Remember do not fix it if it is not broken, so do not change this app.

Love this clock but wish I could add it to my Home Screen.
It is about 2.5 seconds ahead of UTC(NIST) and kind of defeats the purpose of having it for me because I’m trying to sync accurate time on my watch with UTC(NIST) for AWS. So’d you’re in the US and want accurate time, don’t count on this app. If you want a clock and don’t care about accuracy in the US, then it works fine.
If you search for Atomic Clock on the App Store, everything you find but this is mostly junk. With configurable NTP server, cross platform support, and perfect synchronicity; it’s worth every dime.
My go to app for atomic time. I use it for setting my watches and have done so for years.
This app is beautiful and well-designed. The clock face is unique but easy to read, even the seconds indicator, even from a distance, and attractive in an art-y way. The app itself is totally iOS native and doesn’t seem to be a cross-platform port. It’s perfect!
When are you going to update your software?
I got this as an alarm clock. I set it to sync only daily but it ignores that setting; it syncs each time I look at it, which I assume is blocking the alarm. There is no help function or “contact us.” It is utterly useless (unless you leave your phone screen on overnight).
Works perfectly every time. This is my go to for setting my clocks and watches. This app has a beautiful simplicity that I really enjoy.
My only wish would be that you can set a different alarm for different days.
App is always there to set my watch by, couldn’t ask for more.
Also the best for setting the time!
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.
It just works so well. It is accurate, simple user friendly interface allows one to easily and accurately set clocks and mark precise time.
Perfect for a confused guy like me who has a 20th century mechanical watch but wants it to be accurate to the second when I set it.
Always accurate- easy to use to update other clocks
I am a horologist and use this app to set all kinds of clocks, including tower clocks, grandfather clocks, and many more. It’s fun to tell people that my clocks are set to the pulse of a cesium 133 atom. I also like their little surprise digital shows on New Year’s. You have to wait a whole year to see it though. I also like that the app is very customizable.
I love this program because I am a watch enthusiast and am always setting my automatic mechanical watches. I have been looking for a fun atomic clock, and this checks that box.
App Is As Described. Clock Accuracy Is Truly Spot—On When Synchronized Via the Internet. Zero functionality issues. I use this app to synchronize all of my watches & other clocks to.
Have used it for many years. Especially useful for setting watch to the second.
I use this app so all of watches stay the exact time.
Truly accurate clock app!
A request: 1 PPS sound. Preferably a standard 1 PPS signal output on the iPhones audio port. Allows user to compare a local 1 PPS source to that of the iPhone’s GPS generated 1 PPS.
I find this app useful as time is important to me and I can not always use WWV. I have used it many years as it works so well and seems to be accurate.
I really love this app, I love its purity and spirit. Plus, it gives me really accurate time with Audible. feedback to set server dates and times. Thank you.
This app has only one main use for me: New Year’s Countdowns. It’s been a family tradition for ten years to use this app for our countdown because of the cool little thing it does once it’s 10 seconds til midnight. I also used it to get 2/22/22 at 22:22. Fun times! I hope this app never goes away.
I like to know exact time on occasion.
Does what it’s supposed to do.
I have had Atomic Clock for years now and love it as much now as I did when I first got it! It is on my bedside every night. It is very dependable!
I have a small collection of manual wind watches. The Atomic clock is the best when it comes to setting my watches. It’s also kool to know I am using the most accurate time piece possible. I tried to wear my iPad on my wrist to use the clock as a wrist watch, but people laughed. They laughed at Copernicus too. I recommend this app as a must have on your mobile devices.
It works keeps time. What more do you want.
This is a great app for those of us who cherish time as the valuable commodity it is and who desire perfect accuracy.
I love this atomic clock app! The display is beautiful and easy to use, and I love that I can customize the colors to my own favorites. And there’s a special animation for New Year’s Eve! Also, I had a question once, and Markus got right back to me with the answer I needed. 👍👍
My go to App whenever I’m trying to synchronize the clocks on my digital cameras so that I can edit images by the time stamp accurately.
It tells it.
I’ve I used this clock for 5 years and I love it! No issues ever.
The best time app
Good job!
This app is perfect for those of us who like to have all the clocks in our house synchronized.
When I need to set clocks around the house, I use this app. Love that you can select colors and the seconds are measured with dots around the dial with a clear digital time in the middle that also shows the seconds.
Rewriting the network code to work well with IPV6 should show EVERYONE the dedication that these people have for an app that hasn’t charged anyone ANYTHING extra for all these years! I’m going in for the “love it” tip level, because if ANYONE deserves TANGIBLE praise, it’s these people. I encourage everyone to do the same!!! And, here’s the older reviews that STILL apply!!! To add to my original review, I really appreciate the constant updates of this app. It really shows the way "real" developers work and stand by their products. These guys (gals?) are NOT the stereotypical "hit and run" app developers. It takes REAL INTEGRITY to stand by an app from pretty much the start of the App Store (and we need all the integrity we can get these days, no matter where it comes from! ;-). I'm not sure why, but the recently added "440 Hz" mode sounds particularly cool (or maybe familiar?) to me. Give it a try, but make sure you wait until the minute changes and you get the "alternate" tone.
Thanks I love you app
App is straight-forward with a professional appearance.
The centering problem mentioned below in the original review, corrected itself within a day so I gave it all but one star only because I was still missing the feature of multiple alarm settings. The precision is a help at work as I frequently use this clock to reset the time during laptop repairs. The design is very pleasing! The clock display is not centered on the screen so part of the clock is not visible. I just purchased an iPhone 12 Pro and was looking forward to using this precision clock. Also it seems that only one alarm can be set at a time which is a disappointment since most alarm clocks can have multiple alarms set at once...am I missing something? I would give this app a higher rating if I could even see the whole clock.
I love this app.
For stretching before and after movement, I time how long I hold the various stretches with this app simply by remembering the seconds count once I feel I have proper form. I can focus on my body and not have to interact with my phone.
By far the best and most accurate time information available!!!
It’s been great to have a reliable source for setting a clock.
I like the idea of a precision clock and it works well although at times it seems to take a long time to connect to the server. I would like to see more options for how the clock is displayed . I’d also like to have other color options.
