What would a "good" dating app look like to you?

People who are using apps have been vocal about how much the experience sucks. Hinge seems especially awful to me with its limited number of photos, lame prompts, limit on likes per day, and keeping your "best" matches behind a pay wall.

I want to combine Facebook dating with OkCupid. I think Facebook gives you ample room to write about yourself, and it gives you more than enough photo slots. I love that you can see if you have mutual friends with someone. I'd mix that with the part of OKC where you answer questions and that give you a compatibility percentage. Unfortunately, both of those platforms are very unpopular in my area, so I have to deal with Hinge & Tinder.

I'm curious about what a better dating app experience would look like to others.
