Easy Score Pro is great. It does cost a couple of bucks, but it is fantastic. It keeps great stats and you can share rounds with other people that that the App. You can download all of the courses in KC and most of the places that you travel. It even calculates your Disc golf rating ( the formula is a guess, but it is within about 5 points of my actual PDGA rating). It is updated regularly. I have tried a few and this one is the best I have found.
