StatLap vs OnForm: drawing tools or measurements
OnForm is the video analysis app coaches already know. The Film Room borrows its shape and adds the numbers. Here is what that gains and what it gives up.
OnForm is what most video-minded coaches use: record, slow-mo, draw lines and angles, put two clips side by side, talk over it, send it to the athlete. The StatLap Film Room was built to feel the same way on purpose, because that is what people are used to. The difference is what happens after the drawing.
What OnForm does better
- Sharing and organisation across a whole team, with the athlete and coach in one place and the history kept in the cloud.
- Voice-over and telestration polished over years; it is the standard for a reason.
- Every sport. StatLap knows seven track and field events and nothing else.
What the Film Room adds
- A skeleton drawn on the phone, with knee and hip angles read off the video rather than drawn by hand.
- A form check per event: trunk lean, elbow angle, overstride, ground contact, cadence, top speed with two marks set, takeoff angle for the jumps, and the drills that match what it found.
- One count of what is in range and one thing to fix first, then the last five checks side by side.
- Nothing uploads. Clips and checks stay on the phone.
What it gives up
A single 2D camera cannot see rotation, and a phone tracker is not a lab. The report says when the camera was head-on and when the tracker was too slow to time ground contact, and it treats every number as a trend rather than a verdict. OnForm never claims a number, so it never has to say when one is wrong. That is a fair trade in both directions.

Can you measure sprint speed from a phone video?
You can, to about the accuracy of the two marks you put on the ground, which is better than it sounds and worse than a pair of gates.
