IntervalPulse: Tabata Lab is an offline HIIT, Tabata, EMOM and AMRAP timer with a cycle builder and a full-screen pulse you can read from across the room. Try the live lab below.
Total: 3:50 with a 5s warm-up. Beeps and vibration play where your device allows.
Chain warm-up, work, rest, rounds and cool-down into one cycle, then reorder the pieces until it feels right.
Classic 20/10 x8 and a shelf of HIIT, EMOM and AMRAP starters load in a single tap.
Full-screen colour coding: ember for work, mint for rest, amber for warm-up. Glance, do not read.
A firm buzz on every phase change, so you can keep your eyes on your form and your phone in your pocket.
Your saved cycles and finished sessions live on the device itself. Nothing leaves it.
No subscription, no account, no ads, no access requests. Open it and move.
⏱️ We are a small crew of coaches, tinkerers and tired gym-goers who got fed up with interval timers that nag, track and charge. So we built the one we wanted on our own wrists and phones.
🎯 Our mission is simple: make structured training feel effortless. A timer should vanish into the workout and only speak up when it is time to push or breathe.
💪 You get flexible multi-phase cycles, proven protocols, a pulse you can see from the far end of the room, and haptics that tap you on the shoulder at exactly the right second.
🔒 The value is trust. It works offline, asks for nothing and keeps everything on your device, so every session stays yours.
Push. Breathe. Repeat.
