A simple and efficient timer that will help you during your workouts. This app has been created to be SIMPLE : it’s simple to set up your workout, it’s simple to use so you can forget about it during your training and just follow the sounds.
We launched a new design in november 2014, the app is now more user friendly.

First it was developed for HIIT (High Intensity Interval Training) workouts, a famous method to burn fat in a short & intense workout. But our users showed us you can use it every time you need a timer : running, biking, HIIT, Tabata, yoga, stretching… and even cooking !

• WHAT’S HIIT ? *
  High-intensity interval training (HIIT), also called high-intensity intermittent exercise (HIIE) or sprint interval training (SIT), is an enhanced form of interval training, an exercise strategy alternating periods of short intense anaerobic exercise with less-intense recovery periods. HIIT is a form of cardiovascular exercise. Usual HIIT sessions may vary from 4–30 minutes. These short, intense workouts provide improved athletic capacity and condition, improved glucose metabolism, and improved fat burning.
  This definition comes from wikipedia (http://en.wikipedia.org/wiki/High-intensity_interval_training) where you can find a lot more informations. It explains some very popular program, like the TABATA. HIIT is also a common practice in Crossfit trainings.

• HOW TO USE THE APP ? *
  On the first screen you will set up your workout : preparation time, work, rest, rounds and cool down
  Then hit “Go !”, work and just follow the whistle !
  You can listen to your own music, just make sure you can still hear the whistle.

See, it’s very simple !

• PHONE PERMISSIONS *
  Now automatically pause and resume if a phone call arrives.
  This is why PHONE_STATE permissions are required. The app doesn’t have internet access so there’s no chance of sniffing numbers.
