A free program for Android, by Markus Hollitsch.

This is an interval timer for your daily fitness routine.

The goal of this app is to provide an easy way to keep track of your exercise routine and improve your overall health and fitness. With this app, you can choose the intervals, set the colors, and choose the sounds you like. You can even set multiple timers and use them all at once.

This app is ideal for people who do not have a fitness tracker. It is also great for people who want to be more active and need help keeping track of their workout routine.
