HIIT and circuit workouts collapse into chaos the moment you lose track of the round count. A timer that knows the sequence means you never have to pause and ask “wait, was that the last one”.
Build custom work and rest rounds with audible beeps through Web Audio, so the sound, not your counting, carries the workout. Set the round lengths once and run the whole sequence hands-free.

Bottom line: program the rounds, let the beep carry the schedule.
Your turn: use the tool free here, no signup, nothing leaves your device.
