📝 About this app
Interval training is one of the best methods to enhance your physical fitness and burn calories and is therefore a basic part of many physical exercise and workout sessions. It is broadly defined as repetitions of high-speed/intensity work followed by periods of rest or low activity.
This application helps to manage and control the intervals. Just define the duration of the work and relax periods and the number of cycles you want to do. You can choose whether you want audio feedback by alert or sound. So you can listen to your music without monitoring the screen.… View full description on the official store →
