Why HIIT works

High-intensity interval training delivers maximum results in minimum time.

Burn More Calories

Torch calories quickly with intense bursts. HIIT burns more in 20 minutes than an hour of steady cardio.

Save Time

Get effective workouts in under 30 minutes. Perfect for busy schedules — no gym required.

Afterburn Effect

Keep burning calories hours after your workout ends. HIIT boosts your metabolism like nothing else.

Built for simplicity

No complicated setup. No distractions. Just you and your workout.

Timer Interface

Start Instantly

Open the app and go. Default Tabata settings are ready — just tap start. Customize intervals anytime with intuitive controls.

Workout Interface

Your Music, Your Pace
