Whether you're shadowboxing at home, hitting pads with your coach, or sparring at the gym — RoundBlitz keeps your rounds tight and your rest honest.

ONE PRICE. EVERYTHING INCLUDED. Buy RoundBlitz once and the whole app is yours forever. No subscription, no in-app purchases, no locked features, no ads.

HANDS-FREE GESTURE CONTROL

• Start, stop, restart, or skip a round with a hand sign to the front camera
• Works with your gloves on, mid-combination, without breaking rhythm
• Assign the signs you want: open palm, peace, fist, thumbs up, or pointing
• Runs entirely on your device — camera frames are never recorded, saved, or sent anywhere

TRAIN YOUR WAY

• Set round duration, rest time, number of rounds, warning alerts, and prep countdown
• Start from ready-made presets: Boxing Standard (12x3:00), Muay Thai (5x5:00), or Tabata (8x0:20)
• Save unlimited custom presets for different training sessions

DESIGNED FOR THE GYM

• Giant timer digits visible from across the room — no squinting mid-round
• Landscape mode turns your phone into a wall-mounted gym clock
• Works in the background so you can play your own music while training
• Haptic feedback for round changes when your phone is in your pocket

SOUND LIKE FIGHT NIGHT

• Six round alerts: authentic boxing bell, buzzer, whistle, air horn, vintage bell, and crowd claps
• Warning alert before the bell so you know when to push harder
• Spoken-clear countdown into the final seconds of every rest

ON YOUR WRIST

• Apple Watch companion app: start, pause, skip, and reset from your wrist
• Wrist haptics and alerts on every round change
• Keeps the watch screen awake through the workout and logs the session to Health

AFTER THE BELL

• Round-by-round workout summary with total work time, rest time, and estimated calories
• Repeat the session with one tap

PRIVATE BY DESIGN

• No account, no sign-up, no trackers, no analytics
• Everything stays on your device and the whole app works offline

BUILT FOR FIGHTERS RoundBlitz was designed by people who actually train. Every decision — from the oversized digits to the one-tap start — was made to keep you focused on your workout, not your phone.
