iphone golf app

Try out 'Shot Difference Calculator'. Find it on the app store.

Weather for golf is really good...it is nice to see what the weather forecast is for the course in advance.  The best couple of apps I have got are Golfshot GPS, and Golfplan, and they both interlink.  Golfplan looks at your stats and gives you drills to work on in practice, and Golfshot is a GPS program that is very accurate, and it also maintains your scorecards with all additional stats (putts, FIR, GIR, Sand shots etc).
