Coollang tennis sensor and app

The sensor is of little value, It does not recognize the shots properly and provides no spin, sweet spot analysis. The speed estimations are way off and it only provides a summary instead of a shot by shot view.
The App is even worse, The video sync does not work. it is useless to film your shots. The video recording does not work properly with my iphone 8. And when i try to play aa video it shuts down the app.
Worse sensor app combination ever. Complete waste of money
