As a relatively new golfer these sensors and the data gathered and presented in the app are extremely helpful to the improvement of my game. Additionally, the club recommendations and the smart distances that take into consideration wind, humidity, and shot angle (up/down) are great while on the course. The sensor and app interaction isn’t perfect. But, it’s close enough. I tend to take a look and make sure it has recoded the correct number of putts (its most frequent incorrect data) after each hole. I do have to babysit the app a little and do a small handful of edits every round. Every once in awhile the app crashes on iOS requiring me to restart it and do an edit to add the shots that it missed - the nice thing is that I do get a notification when that happens so I’m not just going on my merry way for a long time without the app tracking shots. That said, I still think it’s phenomenal. As a software engineer I am very impressed by both the software itself, as well as the hardware integration with the sensors.
