Burst is an interval timer and a field-test logbook. Free, no account, in 10 languages. EVERY INTERVAL FORMAT Work/rest intervals, pyramids, distance sessions, Tabata, HIIT, boxing rounds, circuits. Set durations on a wheel, name the exercises of each round, add a warm-up, and see the total time before you start. RANDOM BEEPS Random-cue mode drops unpredictable signals into each work phase, at three intensities. Train reaction: strike on the beep, sprint on the beep, change direction on the beep. A feature you will not find in a standard interval timer. FIELD TESTS, WITH THE MATH Léger 20 m shuttle run (beep test), 30-15 Intermittent Fitness Test, Gacon 45/15, Yo-Yo IR1 and IR2, Cooper and half-Cooper, 2 km, T-Test, repeated sprints, BOLT, FTP.

ONE PHONE FOR THE WHOLE TEAM In team mode you enter up to 40 names before the test. During the run, tap the name of whoever stops: each athlete gets their own level and aerobic speed, and the ranking goes into the history. Built for PE classes, clubs and strength coaches. YOUR SESSIONS WITHIN REACH 90 ready-made sessions, sorted by sport and by energy system (VO₂max, threshold, anaerobic, recovery), search, filters, and favorites to bring back your own intervals in one tap.
