If anyone wants to take a crack at it, here what I would advise you build: A simple app that asks you your very very basic info (name, picture, age, location, add 20 word description of yourself). Then simply, simply, simply show me pictures of women. If I like a girl I click "like". If the girls Likes me as well, then we can email each other. I dont need to email her through on your app. You can use the craigslist email style.
That's it. Nothing else. No video chat, IM, levels of communication etc... I don't know about girls, but most guys will only talk to women they are attracted to, no personality match can do the trick if I do not like what I see.
