I was searching for an app exactly like this a few weeks ago. Super glad someone else built it so I don't have to. I think the biggest values I hope to get out of this are: (a) coordination of getting the activity together so that I don't have to deal with flakey friends and (b) connecting me to strangers who also want to play so that I can get a game together even when friends are out of town or don't want to play (I always seems to have more energy than they do). Looking forward to trying this out!
