Form Analyzer

One video. The few things worth fixing.

Film a single rep from the side. The measurements happen on your phone — joint angles, timing, balance — and you get back the handful of faults that would actually change your results, plus a plan for the next two weeks.

Basketball

Analyze your shot

Dip, set point, release, follow-through. Measured against what makes a fast, repeatable jump shot.

Start
Baseball

Analyze your swing

Stance, load, stride, lead-leg block, finish. Choose whether you're training for power or contact.

Start
Ball hockey

Analyze your shot

Stance, load, windup, weight transfer, follow-through. Wrist shot or slap shot.

Start
Tennis

Analyze your serve

Trophy position, leg drive, contact height, landing. The one shot you hit the same way every time.

Check your form

Squat or hip hinge, bodyweight only. Shows what your body did — it does not clear you to add weight.

Start

Your video never leaves your device. Nothing is uploaded and nothing is stored. The body tracking runs inside your browser, and only the resulting numbers — about a dozen angles and timings — are sent to be interpreted.

How it works

  1. Film one rep

    Phone upright in portrait, twelve to fifteen feet to your side. Whole body in frame, feet included, with room above your head.

  2. It measures you

    Thirty-three body landmarks are tracked through the motion, then the key moments are found automatically and measured.

  3. You get a plan

    Three to five faults ranked by impact, a drill for each, and what to work on first. Not a checklist of forty things.

Common questions

Is my video uploaded anywhere?
No. It's measured in your browser and never leaves your phone. Only the numbers are sent onward.
Does it track the ball or the bat?
No. It measures your body only. That means it says nothing about shot arc, bat path, attack angle, or where the ball went — it measures the mechanics that produce those things.
Do I need to trim the video first?
No. It scans the clip and finds the rep on its own. Just keep it to one rep per video.
How long does it take?
Around half a minute to read the video, then about ten seconds for the coaching. Shorter clips are faster.
