Great concept, failure to implement. Very inaccurate.
Loved the idea behind this app, but it’s wildly inaccurate. I did the set up exactly as prescribed with camera 2m away at face level. Lighting was decent(not bad but could have been better). I took five consecutive jumps that were nearly identical, and the results ranged from 24in up to 34.5 inches(I wish that was real, haha!).
