The method

Three steps. One better shot.

01

Record

One side-angle clip of your jumper. No wearables, no markers, no setup — just your phone on a tripod or a friend filming.

02

Analyze

JUMPR tracks every joint a shooting coach watches — knee bend, set point, elbow, release arc — frame by frame.

03

Improve

You get an honest score, the one flaw limiting you most, and a drill built to correct exactly that.

What's inside

A shooting coach in your pocket.

Form Score 0–100

A single, consistent number for every shot, so progress is something you can actually see week over week.

Progress History

Every breakdown is saved. Watch your set point, arc, and balance trend up as you put in the reps.

Targeted Drills

Drills aren't generic. They're chosen from your breakdown to attack the flaw costing you the most points.

AI Coach

Ask why your shot is short or what to fix first. The coach answers using your actual form data.

AI Coach

It knows your shot — not a generic one. Ask anything, and the answer is built on your last breakdown.

Why does my shot keep falling short?
Your release arc is 38° — flat for your height. Lift your set point two inches and follow through up, not out. Try the High-Arc Form drill I added.
Got it. How's my elbow?
Tucked and tracking straight at 91. That's a strength — keep it.

Stop guessing.
