SQNZ – Interval Timer

SQNZ is an interval timer for HIIT, Tabata, circuits and boxing rounds. Set up your intervals once, press start, and follow along by ear: sounds and voice announcements guide you through your phases while your music keeps playing. Build your own timer from a warm-up, work and rest phases, as many rounds as you need, a break between rounds, and a cool-down. Name every exercise, turn on voice announcements, and SQNZ calls out each one as it starts. Or pick a ready-made template and go. Chain several timers and rests into a Flow — say, warm-up, Tabata, stretch — and it runs as one session from start to finish. SQNZ adds your sessions to your training history.
