Misère is an application that scores and tracks games of 500.

You can see Misère in action here.

• Never forget how many points a bid of seven hearts is worth!
• No longer rely on anecdotal evidence about how much better you are at 500 than your siblings and cousins!
• Don't worry about forgetting the score because it's 1am and you're exhausted after been playing non-stop for five hours!

500 is the inevitable card game dragged out for serious, no-holds-barred tournament play at practically every family gathering I attend. I was sick of keeping track of scores manually, and felt like there was a wealth of data about bids and scores waiting to be collated.

Players belong to a single User, so two friends can't both run Misère accounts where either account updates the "shared" player stats. It's possible if I reimplement the model using a join table, but I can't think of an elegant way for one user to share his players with another.
