AI Sports Coaching on Android: Video In, Form Notes Out

2026 review velocity in run, golf, tennis, boxing, and basketball coaching is not “another AI video app.” It is film myself → get a cue. Models got cheap enough that new packages can ship one sport well and collect reviews before a suite arrives.

This brief is part of the Android problem-space map. It is here so we can measure interest — opens, read depth, and related clicks — before anyone writes an app spec.

What people do today

People record with the stock camera, send to a coach on WhatsApp, or guess from YouTube. Generic AI video tools restyle the clip. They do not name a hip angle or a missed split.

Who already won the obvious version

Nike/Strava-class training, Golfshot/Arccos-class golf, HomeCourt-class basketball, generic pose-estimation toys, CapCut. Platforms will absorb “count my reps.” They are slower to own one amateur sport’s language.

Where a small team can still work

Pick one sport and one cue (run cadence, golf takeaway, tennis toss). On-device pose if you can; cloud only if you say so. Output a short note + overlay, not a chatbot. Thermal limits and mid-range GPUs are the product constraint.

How to validate before you build

Watch which queries keep volume after a model-hype week: “analyze my golf swing” vs “AI video.” Scrape reviews for “wrong sport” and “needs perfect lighting.” A prototype should finish one clip on a mid-range phone. If you need every sport on day one, you are in CapCut’s race.
