Camera-powered boxing training
Stop shadow-
boxing. Start
swinging.
Uppercut turns your phone into a corner man. Point the front camera at yourself, throw real punches, and it reads every jab, hook, and combo in real time — no gloves, no sensors, no wearables.
Requires iPhone, front camera, and a bit of room to move.
Three ways in
Pick your fight
Train
A guided ladder of pad combos, from your first jab to full six-piece combinations — each level unlocks the next.
35 levels
Fists mode Beta
Timed rounds where moves come at you — punch, dodge, and keep your hands up before the clock runs out.
Timed rounds
Create your combo
Tap the body to build your own sequence, set the pace, save it, and run it back whenever you want.

How it works
1
Calibrate
Set your stance — orthodox or southpaw — and let the app learn your reach.
2
Choose a mode
Work the ladder in Train, race the clock in Fists, or run a combo you built yourself.
3
Throw hands
The camera reads your punches live — sound, haptics, and a voice coach keep you honest.
Punch sensitivity
Tune how easily a punch counts as a hit — independently for Train, Fists, and your own combos.
Your corner's waiting.
Every mode. Every level. One app, powered by the camera you already have.
