The DigiCue App communicates with the DigiCue BLUE wireless billiard training device. The DigiCue BLUE is like having your own personal coach giving you immediate feedback on every shot that you shoot by alerting you with vibrations when it detects any inconsistencies in your stroke. It also sends information to your smart phone or tablet and gives you detailed results about multiple aspects of your game. The parameters are fully customizable allowing you to focus on what is important to you. For more information please visit www.digicue.net.
