Huge Timer Stopwatch Tabata

You can customize the app screen, by choosing for example font, colors, and device orientation
The app runs also in background. A notification will alert you when the timer has finished.
The app is free. There is only one Ad in the settings screen, which is therefore absolutely non-invasive.

This app is new. If there is any problem, instead of give a bad review, please send me an email. I will try my best to resolve any issue.
