Your video is analysed on your device. It is only uploaded if you save it to the community.
So the analysis does not fail
  • Open in Safari or Chrome, not inside Instagram or TikTok.
  • Trim to just the climb. Under 60 s works best on phones.
  • Stay on this page and keep the screen on until it finishes.
  • Use the original video from your gallery, not an edited or downloaded copy.
  • Slow or stuck? Close other apps and try again on Wi-Fi.
Trim Keep only the climb. Shorter videos analyse faster and fail less.

Display options
  • Skeleton — the white lines joining your joints, so you can see your body shape in each moment.
  • Center of mass — the yellow dot: the balance point of your body. The dashed line shows where gravity pulls it.
  • Contacts — circles on your hands (blue) and feet (green). Filled = on a hold, hollow = in the air.
  • Base of support — the green shape between your contacts. If the yellow dot leaves it, it turns red: you are off balance.
  • Analyzer highlights — red or yellow rings on the body part a tip is about, plus the tip at the bottom of the video.
  • Muscle load — coloured bands on arms, body and legs, and the live bars in the corner: green = relaxed, red = working hard.
  • Holds — thin circles on the holds of your route colour; they thicken when you use them.
