Track Workout Timer

This stopwatch vibrates upon activation and only runs so long as the start button is held down. As soon as the button is released, your sprint time is recorded and a clock for your rest time begins. When the start button is pressed again, your rest time is recorded.

At the end of a session, your sprint and rest times are plotted on a graph.

An undo button allows you to erase data points from when the start button is hit by accident.
