Atomic Wall Clock

About: Atomic Wall Clock

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.
