Session - HIIT Interval Timer

About this app

Session is the interval training timer that adapts to YOUR workout.

Designed to be clear and simple to use, Session keeps things essential: no complicated menus, no unnecessary settings — just your program, your timer, your alerts.

Whether you're running, doing HIIT, Tabata, circuit training, or any other interval workout, Session lets you build fully personalized sessions: number of reps, duration of each phase, type of effort (sprint, recovery, endurance, exercise, prep).

CUSTOM INTERVAL TIMER

Unlike a simple stopwatch, Session lets you build your own interval training program, phase by phase, in any order you want. Perfect for running, strength training, cardio, or any circuit training with intervals.
