Features
No buttons, no counting in your head. Set up once and just play.
On-device computer vision follows the ball and your mic hears it hit the wall. Reps count themselves — you never touch the phone mid-session.
Lax App knows which hand you're throwing with and logs every rep by side, so you can finally measure — and fix — your off-hand.
Tell it "I'm struggling with lefty catches" and it builds you a workout. Powered by Apple's on-device models — your data never leaves your phone.
Set rep and time targets and the session counts down. Hit your goals and Lax App tells you the moment you're done.
Every session is recorded with your live stats on screen. Rewatch your form, then save your best sessions to your phone.
Reps per day, left/right balance, and time on the wall — week, month, year. Watch your weak hand catch up.
Your Stats
See your reps per day, left-hand vs. right-hand balance, and total time on the wall. Watch your numbers climb and your weaker side catch up over time.
AI Coach
Tell it what you want to work on — "I need to work on my left hand" — and it writes the workout: reps per hand, a time cap, and one tap to start. Runs on-device, so it's instant and private.
Goal workouts
Dial in left and right rep goals and a time limit. The session counts down and tells you the moment you've hit your numbers.
Your history
Reps, time, and your left/right split for each workout — all in one place. Watch your off-hand close the gap week over week.
How it works
Lean it against the wall in portrait, front camera facing you.
Step into frame until Lax App can see you head to feet. It starts on its own.
