Atomic Clock & Watch Accuracy Tool (with NTP Time)

This app is very simple. It works as advertised. The visual design is clean. You can choose a ticking or smoothly moving second hand. That's about it. The app showed that the time displayed on my computer is 0.16 sec. ahead of NTP time: could be better, but amazing all the same.

Very useful and accurate app! I have atomic clocks around the house and this app matches their time accurately. The function of being able to record your watch time at various intervals to judge its accuracy over time is very useful. The layout of the app is great in my opinion. Worthy of five stars from me!

This app helps me to keep the watches in my collection at the correct time, no longer do I refer to my satellite watches. It made me realise that even my phones' time is off! Like it so much that I bought the all-inclusive Platinum pro version! Enough said. UPDATE: Developers, could you make the "RECORD TIME" button in the "New measurement" screen bigger and round please. While concentrating on the SEC hand of my watches, I could sometimes miss tapping the rather small one currently available.

The watch is great. What I don't like is that after upgraded to remove the ads, which was removed, I have to pay to have for advance settings that includes color. After the second upgrade the app remained the same, no additional colors, no dark mode, just the same. Whatever you sell, if you are paid what you ask you have to deliver.

Phenomenal, this is something that I didn't even dare to imagine as a possibility. Now, when it's here, I see some aditional options, that also might bee included. First, the option to manualy set, with a single keypress, the phone's local time, according to the Atomic. Second, the option of doing this setting automatically, from time to time, momorizing and calculating the average offset, so that it can be done even offline. Other than that, this application is perfect.

It does just what it says. Has Atomic clock. Shows second hand making it easier to set a watch by. Also you can hit a button when your watch is on a particular time and it calculates the difference between atomic clock and your watch to gage accuracy. Lots of different options for paid version depending on what you want to use as far as options. Perhaps a bit price for an app, but it is refreshing to have an app that does not have adds.

Awesome App in many different formats. Had no idea that one is able to synch their watches with the app to test how well the watches keep time ie milliseconds, seconds, minutes of detailed analysis. That's a cool aspect of the app. Also reflects one electronic device(s) current time against the Atomic clock. Utilize this unique app more than I thought. Initially thought it was more of a gimmick but far from that. Impressed with the different features and capabilities of it.

It is a really great app that displays time accurratley. However, if your looking for different color themes, I recommend you purchase it (as I did). Large, clear display and has operated trouble free. I really like the timepiece feature where you can set different watches, remember them and compare for accuracy. I really rely on this app as I work in the Transportation Industry. I HIGHLY RECOMMEND Atomic Clock & Watch Accuracy!

Works really well and very helpful. I've tried a few similar apps but I'm sticking with this one because it's the most well done. Suggested feature... An optional quick entry mode where you can set up a favorite watch from your list and have it right on the homepage, and do a measurement with one click. Right now it takes six clicks. And I find myself measuring my watch a lot, so this would be even more fun with fewer clocks!

I got the platinum edition and like it a lot. I'd like to suggest the capability of adding a photo to each watch profile for quick / easy identification. Would be nice for those with larger collections. Thanks! ETA: In the "My Watches" window, it would also be cool if we could list them in order of accuracy (based on the average of the latest series of measurements). Edit to add another suggestion. It would be nice to be able to add a comment to a measurement. For example, if want to check accuracy with the watch in different positions and make a note of that position... or when the watch was fully wound.

this is a simple and efficient app. It gives you two choices for atomic time, to compare you watch too. I'm trying to time an Invicta Grand Diver, and these things are either right on or like mine, right off! LOL I've been fooling with it for a week now, and it jumps for me from a minute fast per day, to a minute slow per day. I'm right at a point where it can only be moved a nanometer to get it where I need it + or -3 to 5 seconds per day. Couldn't possibly do it without the help with this app

Great tool/app for my new found hobby... collecting watches! Nice to be able to sync all pieces with atomic accuracy. Got another app that actually sends the frequency signal so the wrist watch can sync to atomic! PS. if this can functionality could be added this will be the Swiss army knife app for atomic clock accuracy! Either way I bought it (Platinum), keep the good work!

It would be nice to implement the ability to add commentaries to each timing result. And be able to select the position of the watch, temperature...etc. All these ideas are implemented in WatchCheck app. You can look for inspiration there. But overall, this is the best timing app for watches so far.

I have only been using this app for a short period, but am very pleased with its performance. It has been the most accurate time keeping app i have ever used. I have a friend who is a retired 2nd class wsrrant officer from the army who's job was to service and maintain the nuclear arsenal and had a clock on his wall he said he never had re set. He said it was a nuclesr clock that was sent a signal that kept it set accurately.

Perfect! I app is the tool I didn't know that I needed. Through a series of minor adjustments over a week I allowed me to improve the accuracy of our grandfather clock from it keeping accurate time to an accuracy of within 2 seconds per week. Free version did everything I needed but I was so grateful I purchased the premium version. Worked great for me and I highly recommend.

I use this primarily to set time for my SEIKO Solar powered wrist watch. I set it to the second and it pretty much stays there to the second for months. I like that. Atta boy feelings. Now it's 3/9/22. Still is very useful to set it to the second whenever my clocks/watch need to reflect the changing months and days. I'm happy to say my timepieces are remaining more accurate when I need it to be. Cool

Not much to say. Its an app that shows the difference between your devices clock and (what i assume is) the atomic clock. Apparently it also can sync fancy watches? I DL it for checking my internal network clocks. It doesn't seem to have much of a functionality for that, but at least I know my phone is synced to whatever their clock source is.

Easy to use but have to pay extra for features including more than one watch. Can't delete a measurement which is a problem as the entire operation depends on your hitting a button at a precise moment. If you feel you were off even a little you should be able to delete that one and try again.

Paid for full version but there is a bug, where you add an additional watch and it can't calculate the time difference on the initial watch you add. First watch has 10+ readings, second watch has 2 readings. Both watches says time can't be calculated. Have emailed dev for a fix and will update review later. Another issue for me, is you can't delete a time if there is only one time in the series.

Excellent app. To alert me 10 seconds before the alarm is so useful in so many ways. Bravo. I will add that it would also be helpful, if in addition to the 1 minute alarm, if there were other multiple/repeat alarms like 5, 10, 15 minute alarms. Otherwise, I just love this Atomic Clock.

Good timing app. Some improvements that could be made: Make it so overlay of multiple timing runs for a single watch to compare. Add a note section for each timing run to be able to record things like watch position (laying flat, laying face down, crown up, worn, watch winder, etc.) and allow those data points to compare so that relative regulation can be compared.

I use the app satisfactory for last four weeks w/o any fails. Of course I can't check accuracy of exposured atomic exact time presented by the app, however I am surprised by difference of time in my handy mobil in comparison with this available etalon. Thanks to the creator of this app I can check time difference in my watches when I am out of radio correction signal. Great job?
