I think the most straight forward dating app would be the one for "one night stands" because both people know exactly what they want but then again you would need to demand STD checks for all users perhaps on a monthly basis. This is just my humorous thought experiment idea.
At a time I was thinking with a buddy (and someone from HN) to make an up where you (speak women) can only date me and my friends. For men it would be invitation only.
