## Description

Simple Interval Timer (SIT) is a minimal, easy-to-use timer designed for all kinds of interval training. Set the number of sets, action duration, and break duration to match your workout, whether it's HIIT, Tabata, running, cycling, or stretching. The clean interface avoids distractions, helping you focus on your training. It also remembers your last five configurations for quick switching.

On iOS devices and with SIT Watch, you can run in the background, prevent the screen from dimming, and track heart rate during workouts. Workout data can sync to Apple Health, and SIT Watch can operate independently after the initial setup, so you can train away from your phone.
