NO SUBSCRIPTIONS. NO ADS. EVER.
No premium tier, no in-app purchases, no adverts, no account to create. Download it, use every feature, and keep it forever — for nothing.

READY-MADE WORKOUTS
Start in one tap with six presets: Tabata (20s work / 10s rest x 8), 40 / 20, 30 / 30, a 10-Minute Workout, Sprint Intervals with warm-up and cool-down, and a gentle Beginner 20 / 40 pace.

BUILD YOUR OWN
Set work time, rest time, rounds and sets, then add a warm-up and cool-down. The total duration updates as you edit, so you always know how long the session will last. Save as many workouts as you like in My Workouts — presets are never overwritten when you duplicate and change them.

CLEAR WHILE YOU MOVE
A large phase label, a big countdown clock, a preview of the next interval and a final-interval warning mean you never have to squint mid-set. Pause, resume or reset at any moment.

CUES YOU CAN RELY ON
Sound cues mark every change of phase, with optional 3-2-1 countdown ticks and adjustable cue volume. Haptic feedback lets you feel each interval even when your music is loud or the phone is in your pocket. Keep the screen awake while you train.

YOUR WORKOUTS STAY ON YOUR PHONE
Everything is saved locally on your iPhone. No sign-in, no cloud account, no analytics, no tracking — and it works perfectly offline.

LIGHT OR DARK
Switch between a light background and a black one for early-morning or late-night sessions.
