## What is TimerOK?

TimerOK is a simple, modern and easy to use interval workout timer app for high intensity interval training (HIIT timer). It is more than a stopwatch or countdown clock, it's a timer for stylish people.

You can easily create training sequences so that they run one after another, changing the background color and informing you with sound signals.

Simple app - no headache!
