Maybe. The idea of an app to meeting new people and helping make new friends sounds cool "on paper" so to speak. But in reality, my schedule is usually so chaotic, that I'd probably never actually wind up filling in a time that I was available. I think I just prefer browsing a list of meetings that somebody else has scheduled (or proposed) and then deciding (as late as the last minute) if I want to go or not.

In practice, doing that for Meetup.com meetups is how I "solve" this problem.

Still though, this sounds like it might have some potential. And, hey, if you get some traction for it, you have a very obvious acquirer (if they don't already have something like this) in Starbucks themselves.
