I am on pretty much every app, except Tinder (Bumble, Hinge, okcupid, pof and even muzmatch (im south asian)). I have a bachelors, and I make good money. I've been told that I am a decent looking guy and I have quite a few hobbies. It's easy for me to make friends, so I don't think I fit the programmer stereotype.
I am on these apps with the explicit intention of finding a long term partner and I've made it clear, but it seems that >95% of people are there for flings, fwb or casual hookups.
I am starting to realize that dating apps are broken, if you are looking for a serious relationship - there's just no way you are going to find it on here.
The focus of the study has been on guys with higher education, and from what I've seen girls here are not that well educated. Perhaps this is a small city phenomenon (pop. 1.5 mil), but it's quite shocking to see this disparity (That's another topic).
Take this as you will, maybe it's just me venting or whatever, but it's tough out there and these apps are just not it.
