ROUNDS turns your iPhone into a live punch counter and round timer for shadow boxing and conditioning. On-device camera tracking counts punches and supported movements while you train. No bag, wearable, or Apple Watch required. PUT YOUR PHONE DOWN. START BOXING. ROUNDS handles the timer, punch count, transitions, and spoken guidance so you can focus on the work. BUILT AROUND YOUR WEEK Tell ROUNDS your goal, experience, and how many nights you can train. You get a fight card with your rounds, training days, and a first milestone, plus optional reminders scheduled on your phone. TRAIN YOUR WAY • Start My Rounds: One tap starts your plan. No setup. • Free Spar: Boxing rounds with live punch counting, pace, round length, and rest. • Custom Session: Mix Free Spar, conditioning, Freestyle, and Rest blocks in any order with time or rep targets. Repeat for up to 24 rounds with a subscription. • Endurance: Keep punching and track total output and pace. • Repeat Workout: Start again with the exact setup from a past session. CONDITIONING Push-ups, Squats, Squat Jumps, Burpees, Jumping Jacks, Jump Rope, High Knees, Lateral Hops, and Butt Kicks are counted live by the camera. Freestyle and Rest are timed. REPLAYS AND AUTO-SAVE Recording is optional and off by default. Save a screen replay, with or without microphone audio.

TRACK REAL PROGRESS • Session history and weekly attendance • Round-by-round punch output and boxing pace • Conditioning reps and work time • Comparisons between matching workouts • Result cards to save and share • Game Center rankings and friend challenges • Fight Night design in dark and light TRY ROUNDS Complete three Free Spar or Custom Sessions of up to three rounds before choosing a subscription.

PRIVACY BY DESIGN Pose analysis and punch detection happen on your device. No account required. ROUNDS does not collect camera footage, pose data, microphone content, or names for analytics. ACCURACY Counts are training estimates, not official scoring. Lighting, framing, angle, and speed affect accuracy. For best results, stand 6 to 8 feet back, keep your body visible, and use a simple background. Train in a clear space and stop if you feel pain or discomfort. Make every round count.
