### 1/5 — Great concept, failure to implement. Very inaccurate.

*2020-05-20*

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!).

### 2/5 — Need help!

*2018-12-05*

The app gives me unrealistic/false results.  It says I jump from 70 to 90 cm high but I know that my maximum is around 50 cm.. Tested it a many times at different places and different camera height/distance but I keep getting those very high results.

### 5/5 — Good tool for PE Teachers

*2018-01-12*

This app is a handy and fun way to measure the Sargent jump. Students like it and it saves lots of time in lessons.
