Was really excited to try. Did not log speed, logged every stroke as topspin. Uses excess battery on gear S2 when not using the app.
It doesn't pair with sony watches.
Unable to sync from gear fit 2 to the mobile application...
Can you make one for squash?
Well made and great concept. It would be great to have some more features and a better explained graphic after match. But you're on the right track. I'm a tennis coach and really like it!
I can develop the app into a professional sports tool and then market it in the USA. Contact me via LinkedIn.
