This is a stand-alone watch app for the DigiBall. It does not require another device to operate. The DigiBall® is a patented electronic cue ball that automatically detects the exact tip location when hit. Because it uses gravity as a reference there is no need for manual alignment (unlike traditional training balls). Information is sent wirelessly via Bluetooth® to an Apple device. All balls are perfectly balanced, perfectly round, weigh the same as a regulation ball and made from Aramith® resin. The DigiBall uses a shock-resistant automotive-grade IMU on a custom circuit board that is further encapsulated and ruggedized; break-shots are no problem. Each ball comes with a proprietary charging pad which provides 16 hours of play time per charge. The purpose of the DigiBall is to provide players/students immediate feedback on the accuracy of their stroke when hitting the cue ball. Accuracy is very important for both pocketing the object ball and imparting the correct spin on the cue ball to travel to the desired position for the next shot. Knowledge of tip position accuracy helps guide the player in choosing where to make fundamental corrections, be it aiming, stroke, alignment, focus, or conceptual. Accuracy is key to consistent billiards. See www.digicue.net for more information.
