This is my little motivation to master the challenge.

The app gives you from 01 February to 01 March, the day to be created in seconds Plank Challenge before. In addition, it is to choose any day of the Challenge to train the seconds specified there you free.

During training, you can pause or break. You can not turn off the sound, unfortunately, it already offers your smartphone sufficiently proven ability).

The whole is based on web technologies, so it is "almost" a web page, you can find them also at:
