Velo Lab
Film a pitch side-on on your phone and it measures your mechanics, then tells you the one change worth the most mph.
It tracks every frame with pose estimation and compares what your body did with 100 pitchers measured in a biomechanics lab. In the off-season it tests your jump, mobility and strength, builds a 12-week plan from your gaps and injury history, and Claude reviews each week with you.
Invite-only for now.
