I would love to help you guys out, but I'm not sure how to make it make economic sense (i.e.: pay for the server).
As an experiment I did
http://www.tictacwhoa.com. It looks like the ad revenue will result in break-even (that's all i ask for) but the kinds of apps you are talking about require slightly more expensive server space because they need to support cgi (since the score data needs to be stored on the server rather than the client - it's too big for cookies).
After I finish a card game I'm working on (this weekend), I'll consider doing one of these suggestions if it looks like there is enough interest to warrant it. I was already thinking of doing a baseball scorekeeping app (like an electronic scorecard). I'm afraid I don't know anything about golf, so the bowling app is the more likely bet. (Unless for golf all you want is date, holes, par, score, or maybe score/par per hole?)
Interested in hearing thoughts and suggestions on how to make niche apps like these work from an economic perspective. Perhaps putting a lot of these little things on one server and distributing the cost will work.
