Film one attempt. Bolts reads every frame and tells you the one thing to change.
What goes in, what comes out
Seven tricks, one engine. You hand it the clip, the trick you were going for and where the phone was. It hands back what your board and your body actually did, and the one thing to change.

You're landing with straight legs. Bend your knees as the wheels touch and let them soak it up.
You landed away from the bolts. Look down for them as the board comes back level and put your feet where you can see them.
Your front foot stopped halfway. Slide it right up to the nose and pull your back knee up after it.
14 of the 26 measurements come off a single phone, over 453 frames — the board was found in 453 of them. 7 of the rest want a second angle: nothing filmed from the side can see a board turning over about its own length.

It's flying out in front of you. Take your chest to the nose and jump forward with the board, not straight up off it.

You landed away from the bolts. Look down for them as the board comes back level and put your feet where you can see them.

Every measurement here is read off the clip. The lines that turn a measurement into a piece of coaching come from the published work rather than from fitting, and that is the half still being sharpened. Where the measurements come from. Footage: kaggle 120fps, CC-BY-4.0.
Two goes, one frame
Lined up on the tail hitting, at a third speed. Same moment, both clips, so the difference is the skating and not where the video started.

What you get
The measuring is the engine. This is the app it drives — real screens, from the build that ships.
