An idea for the app:  How about a Find a Partner option.  You can fill out that you're a [male/female] looking for [male/female/any].  You want to [control/be controlled/sync].  Then the app could pair you with someone else who's available, on the same FaP section (completely accidental acronym but now I like it more) and has appropriate criteria.  What do you guys think?  If your availability ends, you could cancel your request.
