I just got the Golfer Stats Pro app for my phone. It is easy to use and a quick scorecard, so your not holding up the group. All I enter is Par, Score, Putts, Penalties, Fairway, and bunker. Using that I get over 60 different stats on driving, approach shots, putting and other stats. My favorite stat is Top 3 worst/best holes for the round. It helped with course strategy the next time I played it. You can also break down the stats by viewing them overall, by the course you played (helps when playing the same course a lot), by round and even by year.
The app gives me every stat that I need and then some...
