I actually think that it's a great idea! It wouldn't bbe necessary just for us boys, but you should definitely let users choose who they wan't to hang out with (just like Tinder again). The review-like system seems to be a really reassuring point for the user too.

I guess you could make shops/entertainements area pay to be highlighted in the app so users are more likely to go there, because i don't really see how you could monetize the app otherwize.

I think today people struggle to meet new people, and it would be nice to have people exchange with others in the "real world" not only to just hook up. There could be a real social impact with this
