The 01 Dart Out app is an interactive out chart designed to help 301, 501 and 701 players find the best approach to go out. Configurable options allow you to choose out charts for single out or double out scenarios, and allow you to specify whether single bulls are worth 50 or 25 points. Simply type in the number of points remaining and the app will tell you what to hit with each of your 3 darts to achieve victory!
