I have more than half of my videos still being analyzed! I want my money back!!! ### 2/5 — Cool but glitchy *2025-04-20, version 3.3.7* When it works it seems cool and possibly helpful but it would be nice if we could use the front camera. Also the camera may work at first use then if I try to record another trial the camera isn’t working. I have to exit out and restart the trial for the camera to maybe work. ### 1/5 — Doesn’t work *2024-12-06, version 3.3.7* I subscribed for one month, 0 analysis so far after 10 recorded videos. Waste of time and money. ### 1/5 — Absolute junk *2024-10-31, version 3.3.7* Just tried on my new iPhone, simply does not work. Lets you record only from one camera, after processing, the ai evaluator gives error and deletes the video… Contacted support by email and it came back of undeliverable… I think it is fake ### 1/5 — Low quality *2024-06-28, version 3.3.6* Doesn’t recognise swing but provides 81 mark. Very poor quality. ### 1/5 — Does not work at all *2024-06-03, version 3.3.6* Videos uploaded stuck for a few days at “analyzing” phase ### 5/5 — amazing *2024-05-02, version 3.3.6* amazing ### 3/5 — Cool idea doesn’t work that well *2024-03-25, version 3.3.6* It’s ok ### 2/5 — Analyzing freeze *2023-11-04, version 3.3.6* The app has bug and cannot finish analyzing videos. Pls fix! ### 1/5 — Não carrega o vídeo, só fica em análise. *2023-09-13* Horrível!!!! Horrível ! Horrível! Deveriam devolver o dinheiro. O vídeo fica em análise , já tive vídeo apagado. Enfim não funciona. Achei que seria a solução para análise biomecânica dos meus atletas. Mas realmente não foi. Péssima experiência. **Developer response:** Hi and sorry for your experience. There might be something wrong with the setup, or a poor internet connection.
