Building an app that connects coaching knowledge to your climbing video — not a coach, more like a spotter that points out what's hard to feel from inside the move
Been working on this for a while as a side project. The idea is simple — you film your session, the app identifies moments where technique matters most, and surfaces specific cues based on what your body is actually doing at that instant.
So instead of generic advice like "use your legs more," it gives you things like "pull elbow tighter to ribs to engage lats, reducing shoulder fatigue" or "drive harder through the higher foot to unload the supporting arm sooner." The feedback is tied to a specific frame in your video, not a general tip.
I think of it more like a spotter — someone standing behind you who can see what you can't feel from inside the move. A coach builds a long-term plan for you. A spotter just says "hey, did you notice your hip was far from the wall right before that reach?" That's the gap I'm trying to fill.
Right now it detects the skeleton, identifies holds on the wall, and combines that with a knowledge base built from real coaching sources to generate the feedback. It also picks out the 3 most critical moments in your climb automatically so you don't have to scrub through the whole video.
Still early and plenty of rough edges. Curious — what would you actually want something like this to tell you about your climbing? What feedback do you wish you could get without having a coach standing next to you?
