Ryan, if you haven't found it yet, there is an Android App called "Easy Score" for golf scores, and it has a selection for disc golf. You keep the names of the courses on file and just select whatever one you're playing at the time. It keeps track of how long it takes to play each hole/round in addition to keeping score.
BTW, this new EVO 4G is the shiat. There's even an App I found that turns it into a metal detector-- I was able to find where they buried Ronnie James Dio in no time flat!
