One of the most useful DG Apps

Finds the basket by itself. No pacing it off and no waiting on GPS. For quick rough estimates it’s perfect, and it’s more than accurate than you’d think, while reducing the need to carry one more item in your bag.

Awesome App

I started using this recently to help me understand my throws and better gauge the power I’m using. It is fantastic so far! The calibration was super easy and fast, but the general usage is even easier. This is well worth the cost if you’re looking to up your disc game.
