ServeLab

Three issues - 1 - data and screens get clipped when viewing on phone so can’t see all info. Nothing I can do to fix this and very frustrating. 2 - requested to be compared to a female player and always compared to a male player (usually Jannik, i wish i was a 6’4” male pro player, i am not). 3 - if I reverse the camera to shoot my serve the AI somehow puts the racquet in my LEFT hand and treats me like a lefty. It’s bizarre.

I echo the other review, though maybe it has gotten better by now with a larger dataset to work from. When I used it in Oct 25, it was not able to accurately distinguish different parts of my body and joint angles even if I set up everything perfectly with good lighting and distinguishable clothing. I thought I was going crazy trying everything to change my stroke until I realized it was not reading my stroke right in the first place. Additionally, although Mark is a good researcher and can identify problems with technique, he isn’t an expert coach in fixing those problems, so the tips for improvement are quite limited.

his product feels completely raw and underdeveloped — hard to believe they’re charging a premium for it. The so-called “AI” serve evaluation gives ridiculous and inaccurate feedback; I even tested it by recording a player who didn’t serve at all, and it still produced detailed “issues” in every stage of the serve. It’s a great idea in theory, but in its current state, it simply doesn’t work. Definitely not worth $60 a month — and by the way, the video processing alone takes a good 15 minutes.
