Just works!
Been using for years and decided to pay up…
It does just what it’s supposed to… great for setting clocks it is!!!

I like the split second display.
Split second display is desirable. I used radio timing in the 1960’ while in the USAF. So useful that a Cesium-beam frequency standard was flown regularly to our sites. I don’t NEED it, but enjoy it. Thank you.
Useless app
I purchased this app to use on the top of my phone while I’m in the background working and I’m not able to do that. I got a unprofessional message from one of the developer, which is not something of a professional company. I simply requested a refund and have not received it. I will all install your app as you requested, but please assist me with my refund.

Useless app
I need to be able to toggle my clock to the top of my iPhone and I can’t. Unless I’m able to do that I wasted my money purchasing this app.
Great iPhone app for working with radio-controlled watches
This app has the most useful handset designs and display options for the iPhone. I use it to gauge timekeeping for all my watches. And I use it in conjunction with the Clockwave and Junghans apps for setting radio-controlled watches. atomic-clock apps I’ve seen for iPhones. I use this many times every day. It’s a keeper!!!

Very Helpful App
Being able to sync with different time servers is a great feature. This makes setting watches for a synced time very easy! The unlock for premium gives a lot of options. Simple and clean with many options to customize.
Minute beep is late
Update: I’ve discovered if “Acoustic Ticking” is enabled the 5-second countdown beeps work correctly.
Can you explain why on my iPhone 16 pro max (iOS is up to date) the 5-second beep count to the top of the minute is one second late? The beep starts at 56 seconds and the minute long beeps occurs at 1 second after the 0 minute. Thanks

Do track me
5 seconds in the app asked to track me. Immediately deleted it.

Great App
It helps me fine tune my Grandfather clock.
The best
I have used this app for several years. It is fantastic and I use it daily to set and track the accuracy of my watches.
1 out of 3!…
One of my top three favorite atomic clock apps!!!
Brilliant App
Brilliant time keeper..
Atomic Clock
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.
Was great, now worthless
They smelled the money. Now its unusable. Advert covers clock unless you pay up. Delete!
Free version not usable
There is a trial version but it’s not usable, because of ads covering the face of the clock. Hard to review. I can hear the ticking though.
Exactly what I need for accurate time
I use this app to adjust time when we change the time in November and March. And periodically when I notice a clock is not perfectly set. I like each clock set to the exact time. Nice features. I’ve noticed a few people mention ads. It’s an ad at top that you can easily adjust to a very small size. It’s usually the width of a pencil. And the developer should make some money for their time and effort. Great app. Many nice features I appreciate.

EXCESSIVE Advertising
Excessive advertising, deleted app.
No button to reject all contents
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, shows the Internet Network Time Protocol (NTP)
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.
