Simply the Best!
I have tried most of the GPSs available for the IPhone and SkyDroid is the quickest at updating and has a lot longer battery life. I also own a Skycaddie and a Garmin GPS and although they are very good they do not update the distances as quickly as SkyDroid does. SkyDroid also seems to have all the golf courses I need.
