Quintic Ball Roll

App crashes when clicking record

I was very excited about this app, and the data seems very useful. However, there are no setup or calibration instructions. More specifically, the wide camera angle makes it so that the only way to line the ball up properly is to “aim” the line at the camera lens—however, the putt analysis clearly shows the ball rolling away from the lens, making the data suspect. I imagine, phone is meant to be aligned parallel to the putting line with the verticals ball line perpendicular to that line. It’s very difficult to know for sure without extensive trial and error, but with the phone situated on the ground, my back starts to hurt quickly. Very cool app, but needs more instructions.

Was really excited about this app however it constantly misreads putts. When I go to set the ball in the desired location, the app will take a video when the ball is not hit. This leads to a ton of frustration with using the app as it will take a few seconds to process the putt only to give you useless data. There is a manual capture mode but it seems like a useless feature because - how am I supposed to manually capture footage and putt at the same time? When the app does read the putt correctly, the data does seem legit and useful. However the app needs major work and I’m very disappointed. I ended up spending the $12/month membership too which I am now regretting. Need the developers to fix this, it feels like the app was very rushed. 1/5 until fixed
