So my experiences are mostly positive.
I don't really like that there is some tech-giant mediating my love life but hey, it also means I've met some really cool people I wouldn't have met otherwise. So it's a relatively worthwhile trade off.
I do like that the apps encourages to people to write down what they are into/interested in and most of the apps don't stigmatise queer or casual or whatever non-normative relationship styles.
Annoyingly the website/app I used to like the most was has completely changed it to behave nearly-exactly like tinder (the same company owns them both, as well as most of the other apps).

Don't see why they call it lonesome.
I'm never lonesome when I go there." Connie Converse - Talkin' Like You
