I haven't used them in a while. Probably a major part of the problem is many people use dating apps as a substitute for meeting people in real life or maintaining existing connections - whether this is their own friends, or even a potential partner. A lot of people use dating apps for the novelty factor, which almost by definition comes at the expense of maintaining their existing relationships or friendships (too 'boring').
There are many other problems with them too. Your bullsh*t filter needs to be on red alert when talking to or meeting people over dating apps, even when dating women. I'd find it too frustrating and exhausting. I can and I've done it... I just really did not enjoy it. I do have an issue trusting people though.
One woman even told me that it's apparently "not my business" whether or not she had a partner already, then proceeded to talk about herself nonstop for the next half hour. I may have asked the question too directly, but nonetheless it's a fair question I think. If it made her uncomfortable she could have responded in other ways. Her defensive reaction really... spoke for itself I thought. So its crap like that that isn't too unusual on dating apps.
Another friend of mine told me how one girl he went on a date with from Tinder was apparently writing a dissertation whose topic was all the different guys she meet up / hooked up with over Tinder. And when he said he wasn't interested in another date she retaliated by saying he was too 'sheepish' for her anyway.
Even if you do meet a decent woman, unless she is either very naive or very (too) experienced or otherwise has no healthy inhibitions, her defences will be up as well for similar reasons mine are and make it difficult for the initial conversation to get traction. I never even got that far however, so am no longer speaking from experience, only conjecture.
This is all anecdotal evidence though. There's plenty of statistical evidence online as well, demonstrating that these sorts of experiences aren't very isolated.
If you are going to use dating apps, then at least do it as a supplement to a normal and healthy social life. Not as a replacement. That will give you a greater degree of emotional resilience / tolerance for the sort of bs you will probably encounter on the dating apps. And apparently, I hear that many men are even worse. I haven't tried dating men and don't intend to, but already am pretty sure that occasionally I was talking to men pretending to be women by using their photos. One asked me if I "live alone" and want to meet up in a park just the two of us. That one was over Facebook actually.
