Bouldering video analysis

See how you climb.

Film an attempt on your phone. Sendo draws your skeleton on the video and scores how you moved, so you know what to work on next session.

Invite-only and free while in testing.

How it works

Three steps, no extra gear.

  1. 01

    Film

    Prop your phone up or hand it to a friend and film the whole problem, from the start holds to the top. Up to 90 seconds.

  2. 02

    Analyze

    Sendo finds your body position in every frame. It runs right on your phone or computer, so your video isn't sent anywhere to be analyzed.

  3. 03

    Improve

    Get scores for body position and movement, watch your skeleton move on the video, and see your progress over time.

What you get

Numbers you can climb with.

Every climb gets an overall score and eight measurements of how you moved. They're measured against your own body, so they work at any height.

Body position

Straight arms
How often you hang on straight arms, which saves energy.
Hip position
How centered your hips sit over your feet.
Balance over feet
How often your weight is above your feet.
Body tension
Sudden foot cuts and swings: signs of losing tension.

Movement

Flow
How much of your climbing time you spend moving rather than paused.
Pauses
How long you stay still, and your longest rest.
Foot precision
Whether your feet go on first time.
Readjustments
Small repositionings of hands and feet after placing them.

Filmed with one camera, so these are estimates, not lab measurements.

Privacy

Your climbs stay yours.

Your videos are analyzed on your own device and stored privately. Only you can see them.

  • Analyzed on your device

    Sendo works out your body position right in your browser. Your video isn't sent to an analysis service.

  • Private by default

    Your videos and results are only visible to you. There's no feed and no public profile.

  • You're in control

    Remove a video any time and keep its results, or delete a climb completely.

Questions

Good to know.

Is Sendo free?

Yes. Sendo is a free, invite-only project while it's being tested.

What do I need?

A phone or computer with an up-to-date browser, like Safari or Chrome. No app to install and no special camera.

How should I film?

Keep your whole body in frame from the start holds to the top, film from behind rather than from the side, and make sure the wall is well lit.

Does it work on any wall?

Indoors or outdoors, on any angle. Balance matters most on slab and vertical walls, and Sendo's explanations say so.
