HIIT-timer app for iPhone and iPad

HIIT-timer is a timer to support your high-intensity interval (HIIT) training - also known as high-intensity intermittent exercise (HIIE) or sprint interval training (SIT).

The timer supports four different sections:

- Warm up

A complete interval consists of a high and a low intensity section and the number of passages is adjustable.

The app provides different sounds, even 3-beeps and 5-beeps to indicate the and of an interval section.
