This is a basic indoor lap timer with easy to read total laps and total time. Touch anywhere on the bottom 2/3rds of the screen (just not the word in the top left corner) to start and mark each lap and to continue after a pause. The top left word is used to start, pause, and end the exercise. At the end, the app will display each lap's time in a scrollable format, plus the total time and total laps.
