Professional basketball players perfect their shots with advanced analytics. Now you can access one of the most important shot analytics with The BallHawk by RoViz LLC. The BallHawk will measure your shot’s angle of entry above the rim. Basketball researchers have found that this needs to be around 45-47 degrees above horizontal for the best statistical chance of making the shot. Download the app, put your phone on a tripod, and shoot away. See the angle on the screen and hear it through your phone’s speaker or bluetooth headset! It’s as easy as that.
