Yes, if you have the iPhone, you can use it as a digital golf scorecard. Open up this site in your iPhone.
If you just can’t figure out how to use that pencil that comes with your golf scorecard, or your hand writing is not quite up to par, then there’s always the iPhone golf scorecard.
This application allows you to keep scores for up to four players. You simply tap the names of your foursome into your iPhone and then tap in the corresponding scores, your iPhone will take care of keeping everything nice and neat and add up your score at the end of the round.
