Fully customizable timer for interval training. By default, the timer is configured to training for the TABATA Protocol. (8 sets of 20 seconds of workout , 10 seconds rest), but you can customize any workout time, rest and preparation. Also separately configurable music of workout and rest. Countdown before the end of recreation and training with vocal accompaniment does not allow you to keep track of time on the device, which makes our application more convenient.
