Golf Scoring System 3.0
the author of this app says:
A Golf Scoring System that supports up to four players and allows for the entry of score data, such as strokes and putts, as well as flags.
Course data (par and handicap values for each hole) for up to 15 courses can be categorized for those courses you play frequently. And now, you can also keep track of additional yardage-to-course data.
A scorecard, player stats and a leader board can all be displayed, too.
