Free iOS WOD timer

Tabata timer

How GRIT runs a Tabata

Pick Tabata — GRIT loads 20s work / 10s rest × 8 by default, with the work phase in green and rest in red so it's obvious across the gym. Change any of it (work, rest, rounds) for free; SmartWOD gates custom interval editing behind its paid tier.

1. Open GRIT and choose Tabata.
2. Keep the classic 20/10 × 8, or customise work, rest and rounds.
3. Start — green means work, red means rest, with a beep on each switch.
4. Read the big landscape clock from across the room.
5. Log the movement and how it felt.

Example workouts

• Tabata squats — 20s max air squats / 10s rest × 8.
• Tabata push-ups — 20/10 × 8, count your lowest round.
• Double Tabata — 8 rounds squats, 1 min rest, 8 rounds burpees (GRIT lets you build it free).
