Right now I'm in the process of trying "TeeDroid Caddy" and "How Far Am I." TeeDroid has been really good for me so far, GPS, scorekeeping, shot keeping (distances, club used, where landed). Anyone golfing should at least try this one out. How Far Am I looks good, but I haven't used it much since it doesn't have as many of the courses in my area and I'm too busy to add them right now. It's more of a standard rangefinder app. They are both FREE. With TeeDroid, I actually shut off GPS between shots and holes when I could while leaving the app running in the background. It seemed to save battery (I used a GPS toggle on the Power Manager widget and then long pressed the home key to jump back and forth). Good luck, let me know what you think.
