Changed My Game
When I decided to work on my game and play more, I found this app to help me overcome all the bad tips, and lack of knowledge, i suffered from.
I went from a 30 something H.I. to a 24 pretty quickly. I have taken lessons since then and improved more, but this app got me on my way.
I could use this app when on long cross country flights, so it worked into my schedule, too.
