About
Cornerman is your pocket boxing workout.
Prop up your phone, start a guided round, and Cornerman calls out real boxing combinations as you go: jab-cross, jab-cross-hook, double jab to the body and back. No need to think about what comes next, just keep up with the callouts. No gym, no partner, no gloves required. Just you and the work.
NEW: IT WATCHES YOUR FORM
Cornerman doesn't just count punches, it watches how you move. After the bell, it breaks down your round and flags common form mistakes like dropping your guard or standing too narrow, and shows you the exact clip where it happened. See it for yourself, then clean it up next round.
YOUR ROUND, BROKEN DOWN
Every session ends with a report: total punches, your jab / cross / power mix, and the form issues Cornerman spotted, so you always know what to work on.

Prop your phone against a wall and step back so it can see you.
Box. Just follow the live callouts.
Get your report and see where to improve.
Just you, your phone, and the work.
