Pyramid Interval Training 1', 2', 3', 4', 5', 4', 3', 2', 1' fast and in between 1' slow. The app shows the remaining time of the current interval duration. The timer is always counting down for each interval duration. When the time goes to 0 the next interval duration starts. Between each speed change a beep sound is omitted. The training starts with a warm-up until you press the "LAP" button. When the interval training has finished, the app shows the duration of the cool-down time. This timer continues until you stop the training. This app is based on the "Pyramid-Interval" app but has some usability improvements available to Ambit 2 users only.
