NTPSync is no longer in active development. If you like to take over the maintaining, go to and implement fixes. I will only do basic maintenance.

NTPSync is a simple NTP time synchronization app for Android.

To set system time to NTP time you need root access on your device, to just query the time you don't.

• Information can be found in in-app Help screen.
• If you have other problems please report them in the issue tracker on

You can donate money to support the development in-app.
