About this app

This app has two main features:
- it detects and shows exact time (via NTP protocol). It can be helpful if you want to sync time on some of your devices with atomic clock.
- it allows to track accuracy of your wristwatches. It can be helpful if you want to know how exact your wristwatch is. You can share this information with watchmaker and it helps him to adjust your watches properly.

Features in detail:

Atomic Time from NTP Servers

Ratings and reviews

the atomic clock aspect works fine. but the watch accuracy tracking has a fundamental flaw. i records elapsed time, which is only useful for quartz and other always running watches. with automatic watches (i have a large collection) that are worn occassionally, it will incorrectly display accuracy as though the watch were running continuously. this is not useful and wrong. i've written to tom, the developer about this and about two bugs i've found but he has stopped answering me. too bad

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.

This is my "go to" App whenever I need to sync up a time keeping device to a very accurate source. It also helps sync up with the seconds with the Greenwich Mean Time tones. I recently saw you can tie it in with your smart watch but unfortunately you can't back it up without having to pay for premium coverage. I don't like anything with fees attached. There's too many expenses in life already. Other than that it's a great App!!
