A saved analysis example. Play, choose a measurement and follow it to the footage.

Every number is linked to a moment in the video. This saved example is smoothed across tracking gaps; saved analyses show where measurements are unavailable. New uploads return body-movement measurements after you confirm the rider and height. Wave charts in this saved example are not generated for new uploads.
BodyMotion
See where your hands sit, how your stance shifts and how your shoulders turn. Rotate the translucent 3D reconstruction and examine your body position frame by frame.

Look at estimated wave size and how your position on the face changes through the ride. See when you climb towards the crest and drop back towards the toe.
Video only
Start with a clear camera or drone clip.
No wearables, board sensors or special filming setup. Keep the camera steady, give the ride some room and let us turn the footage into a new perspective on your surfing.
Upload your videos, one ride each, several at once. They're kept in your own library.
Open your saved ride, select the rider and confirm their height to start analysis.
We’ll email when the analysis is ready. We estimate body movement and check which measurements the footage supports.
The examples above show saved analysis. Your own ride is ready to replay and mark as soon as it has uploaded.

Free to start
Your first upload is free, including analysis of a ride up to 60 seconds. Choose a monthly plan when you want to add more footage.
Before you upload
No. A phone, camera or drone can work. What matters is a clear view of the whole rider and board, with some wave around them. A tiny surfer in a distant, blurry shot is much harder to measure.
Upload one ride per video, up to 60 seconds each; you can upload several at once. Shorter videos with one ride each give the best results. Keep the full rider and board in frame, and use the original file if you have it; social-media copies often lose useful detail.
Upload your clip, confirm the rider and enter their height. We estimate body movement and save the result in your studio. The current release provides body measurements; it does not generate wave measurements for new uploads yet. Read the science behind the analysis.
Processing time varies with the clip and demand. We estimate the rider’s body movement and check the result before saving it. Wave fitting is not included in this release. You don’t need to wait on the page—we’ll email you as soon as your analysis is ready.
3D body movement, extension, stance and foot spacing, rotation, knee bend and hand position. Wave measurements are shown in saved examples, but are not generated for new uploads yet. Our guide to the measurements explains each one and which plan includes it.
They’re estimates from video, and the footage matters a great deal. We don’t publish an accuracy percentage. Where your clip cannot support a measurement, you’ll see a gap. Use the numbers alongside the footage to examine a ride and compare your own sessions.
Tell us at [email protected] within 30 days of receiving your result. We’ll review it ourselves and put it right, including analysing the ride manually where needed. If you’re still not satisfied, we’ll refund that ride’s share of your monthly payment. See our guarantee for the terms.
Your first upload is free, including its analysis with the detailed Pro measurements. No card is needed and you won’t be subscribed automatically. After that, Starter is £12 a month for five uploads with core measurements, and Pro is £29 a month for twenty with every measurement and side-by-side comparison.
Upload up to 60 seconds of surfing and review 3D body movement, stance and foot spacing in your private studio.
