I've tried various dating apps and websites throughout the years. Result: I haven't even made a friend from any of them. Every experience with one of these apps I had was kind of depressing and humiliating. (I also have a very small potential dating pool anyway, so that certainly doesn't help.)
Here's an idea for a dating app: Successfully identify what people want in a relationship, match based on that. Alice might be looking for a monogamous relationship, Bob might be looking for a one-night stand. The system should not match the two together unless one of them changes their minds.
OKC does just that -- if you take the time to answer the match questions they offer.
For example, regarding a relationship vs. one night stand, there are the questions "About how long do you want your next relationship to last?" and "Say you've started seeing someone you really like. As far as you're concerned, how long will it take before you have sex?". Assuming both parties have answered those questions (and done so honestly) it's pretty easy to get a good idea of what each side's intentions are.
Also, I believe that if you pay for their A-list feature, you can actually filter out profiles based on answers to these questions, rather than needing to compare answers manually.
I answered over 1000 questions honestly on OKC and the matches were all pretty terrible. That could be simply that there is nobody I'm compatible with.
A lot of the questions are pretty terrible, it forces one to cram their opinions into 2/3/4 choices. The moral quandries with "this is wrong / this is right" are the worst
Your described feature sounds like something that isn't too hard to find. In okcupid people can specify a subset of something like friends, long term dating, short term dating, and casual sex, then filter on what others are looking for.
I don't mean what they'll lie and say they want, I mean detect what they actually want. It's not nearly as easy. ;)
Maybe it's just Orlando, but most of the gay folks I've talked to were very NOT monogamous, but many pretended to be for the sake of managing perceptions and increasing their chances of being contacted.
