About this app

Turn your old android phone / tablet into an accurate atomic digital wall clock, with largest font to fit your screen.

Every 5 minutes the app will sync with NIST Internet Time Server (see http://www.time.gov/), to give you the most accurate time.

To verify that the sync works, the app shows the difference found between the device clock and the atomic time, on the bottom right corner.

There is also a Pro version, which offer more options.

The app ignores whether the phone has it's time set to 24-hour time, so even if you want 3pm to show as 15:00, you are out of luck with this app. Other than that, it does what it says it will do.

Can't tell if am or pm. No way to set 24 hour clock mode. Needs options for time sources. The app needs a lot of work to be useful.

Excellent program does what it says! Calibrates automatically stays on the screen and is 100% accurate
