I definitely do think you've identified a problem that needs solving, and your app is looking nice so far.<p>One thing that I've noticed for pick up soccer in the Bay Area is that there are a lot of games listed on meetup.com, but probably way less than 10% of them, since I personally know of a bunch that aren't on meetup. There are also several other websites that I've found on Google over the years that list some pickup games, but still, nothing that is anywhere near exhaustive.<p>The problem that you guys might have is that your app ends up as just another small subset of the games around. If you could figure out how to become <i>the</i> definitive and nearly exhaustive list, there could potentially be a lot of value in it. Think about how Yelp is useful because it has all the restaurants, and how useless it would be if only 10% of the restaurants were listed.<p>Reviews of ongoing games might be useful, as would ratings of skill level and information about the playing surface or number of fields/courts that people could search on. Another thing is that some ongoing games are already pretty full, so some sort of status that somebody could set for the game in terms of "need more people" or "near capacity" could be useful.<p>Lastly, it's been my experience that an ongoing pick up game might have 20-30 people in attendance, but only 1 or 2 actually check in, so you don't want to necessarily count on everyone checking in.
