Shooting Coach

Record your solo shooting practice and get back only the real, repeating flaws — in both your body mechanics and your shot arc. See the problem drawn on your own shot, get the drill that fixes it, and find out on the next set whether it held.

How it works

Record, review, then verify on the next set

Step 1
Record
Shoot a set of about ten. Video records locally — works at a driveway hoop with no signal.
Step 2
Process
Tap once when you're done. The whole set is analyzed in a single pass.
Step 3
Diagnose
Pose and ball-arc tracking find each shot and test it against good form. A flaw only surfaces if it repeats.
Step 4
Review
Watch your shot with the problem drawn on it, read a plain coaching note, get a drill.
Step 5
Verify
Work the drill and shoot again. The app checks whether the flaw moved toward the standard.
What it catches

Seven flaws, each with the drill that fixes it

Body mechanics
Elbow flare
Elbow drifts out of line at release instead of staying under the ball, aimed at the rim.
DrillOne-arm form shooting — three feet out, elbow under the ball.
Body mechanics
Guide hand thumb flick
The off hand rotates inward at release and pushes the ball off line.
DrillBalloon drill — guide hand only touches, never pushes.
Body mechanics
Short follow-through
The wrist snap stops early and the hand drops before the motion finishes.
DrillHold the pose — freeze the follow-through for three seconds.
Body mechanics
Hitch at set point
A pause or reversal in the wrist and elbow just before the ball is released.
DrillSweep and sway — one continuous motion, catch to release.
Body mechanics
Off-balance landing
Feet land too wide or well forward of where they took off from.
DrillJump stop reps — land in the same spot you left.
Body mechanics
Low release point
The ball is released below the good-form band relative to the head.
DrillChair drill — shoot over an obstacle to force a higher release.
Shot arc
Flat or inconsistent arc
Entry angle below the ~45° target, or arc that varies too much across the set.
DrillRainbow drill — exaggerate a higher arc over a raised target.
Arc and body, linked
A flat arc usually traces back to a body flaw — often a low release or elbow flare. When they co-occur, review shows the symptom and the cause together.
What makes it different

A coach, not a stat tracker

Private by design
Video never leaves your phone
All analysis and playback happen on-device. Only flagged still-frames and arc numbers are sent off — for coaching, not storage. The footage stays with you.
Silence is a feature
Quiet when your form is right
A flaw has to repeat across at least three shots before it surfaces. False alarms cost trust, so the app is biased toward saying nothing — which is why you believe it when it speaks.
Measured against good form
Compared to ideal, not your habits
Your shot is scored against an age-appropriate good-form standard built from clean reference clips — so the app fixes what's actually wrong instead of locking in the habits you already have.
Closes the loop
Checks whether the fix held
Same camera, same set-up, set after set — so the shots after a drill are a clean before-and-after. You see the flaw trend down across sessions, not just get named once.
