Your corner,
in a phone
Prop your phone up, step back, and box. Your coach calls the combinations, keeps the clock and tells you how it went. Here’s what happens, from setup to the last bell.


One minute to set up
No gloves, no bag, no gym. The app checks your setup before the first round.
2mbetween you and your phone, with room to step and turn
- 1
Clear two metres of floor
Enough to step and turn. Move furniture, and keep people and pets out of the way.
- 2
Prop your phone up
Against a wall or a book, so it sees you from your head to your hips.
- 3
Sound on, or off
Every call is spoken and shown big on screen. Mute it and you lose nothing.
Start to finish
Tap a part of the session to see what happens in it. Round length follows your level: two minutes for beginners, three after that.

2 or 3 minutes each
The rounds
Your coach calls combinations by number and name, at your level, and sets them big on screen. The camera counts each punch and checks it was the one called. A clap at ten seconds, the bell at the end.
Boxing, by numbers
Coaches call punches by number, and so does yours: one-two is a jab, then a cross. Pick a number to see it thrown.
1 · Lead hand
Jab
Your fastest punch: the lead hand, straight out and straight back.
- Snap it out from the chin; the palm turns down as the arm straightens.
- The rear hand stays glued to your cheek.
- Back on the same line, just as fast.
The usual mistake: Dropping the hand on the way back, which leaves your chin open.
Your video stays on your phone
The camera is read on your phone, frame by frame, and thrown away. Nothing is recorded or uploaded.
