FAQ
Questions
Do I need a punching bag or any equipment?
No. ROUNDS uses your iPhone camera to count punches and reps, so all you need is your phone and some open floor. Add weights if you want to.
How much space do I need?
Enough to step and punch freely, with your phone 6 to 8 feet away so your whole body is in frame. A garage, living room, patio or hotel room works.
Which iPhones work?
ROUNDS requires iOS 18.0 or later.
Is my camera video uploaded?
No. Pose analysis and punch detection happen on your iPhone. No account is required, and ROUNDS does not collect camera footage or pose data.
How accurate are the counts?
Counts are training estimates, not official scoring. Lighting, framing, angle and speed affect accuracy. Stand 6 to 8 feet back, keep your body visible and use a simple background for the best results.
I'm new to boxing. Is it for me?
Yes. Tell ROUNDS your goal, experience and how many nights you can train, and it builds a plan around your week. You set round length and rest, and you can stop any time.
iPhone App
Make every round count.
Open ROUNDS on your iPhone, set it down, and start your first round tonight.
Safety
Train within your ability in a clear space. Stop if you feel pain or discomfort. Counts are training estimates. ROUNDS is a workout tracking tool, not medical advice.
