I made for interval training.

Time to dash before performing the interval training, you will be asked to set the time to rest.

Timer will start 10 seconds after you press the start button. It does not start immediately. I wonder if need time to put away the smartphone in your pocket, etc.? This is because I thought.

Countdown starts timer will start from the start 10 seconds before. Since I made for the road racer, it will be announced in the sound and vibration can be seen even if running in a pocket on the back of smartphone jersey. The number of the interval is not set. Endlessly repeated until you stop the app.
