Description

Burst is the interval timer built for people who actually train.

It's the only timer with TRUE random beeps — unpredictable cues that hit when you least expect them. Choose the duration, choose how many beeps, and the engine spreads them randomly through your round. No pattern, no anticipation. Just react.

RANDOM BEEPS — THE FEATURE NO OTHER TIMER GETS RIGHT

Boxing & combat sports: shadowbox to unpredictable attack cues

Agility drills: change direction the second the beep hits

Conditioning: break the rhythm — your body never settles into a pattern

Reaction training: real stimulus-response work for sport prep

BUILT DIFFERENT

Smart intervals: work/rest, rounds, optional exercise labels

Pyramids: auto-increasing intervals (10s - 20s - 30s - 40s...)

Distance reps: 100m × 10, manual lap stop with split times

Tabata, HIIT, AMRAP, EMOM-friendly templates

Official fitness tests with officially paced audio cues: Beep Test, Luc-Léger, Yo-Yo IR1 & IR2, Cooper, demi-Cooper, 2 km, 30-15 IFT, Gacon 45/15, T-Test, FTP cycling, RSA
