I like GolfShot GPS a lot, have been using it for 3 seasons now. They just released version 3.0 with a few new features. It also seems quite a bit faster on the iPhone 4S. While I did buy the GolfScape, I don't really use it at all. Just doesn't provide me with anything I can't get from the main app. I really like the app for recording scores during the round and the statistics it provides. Tells me I suck at putting and bunker play, and better than my handicap in fairways and GIR. Yardages are spot on the sprinkler heads at my club.
