FitTimer is a straightforward, easy to use interval countdown timer for sports training.
Two timers count down sequentially to allow you to work for an initial active period, then rest for the next period. Then the sequence is repeated as many times as required. This is a popular method for high intensity sports training.
The display counts down the remaining time for each period and the number of repeats. Vibration feedback is given at the end of each period.
The number of repeats, the active time and the rest time can all be changed on the settings page.
