I know a few women that use Tinder: they are alone, late thirties and never got anything serious out of Tinder, but they use it to reassure their attractiveness by the continuous flow of likes they get. It is a morale booster, nothing more.
I also know a bunch of couples that met on tinder, but it's all from 3 years ago. I haven't heard of someone else who has been successful in finding a long term relationship on Tinder since.
Everyone else has moved on to a better dating site, like Bumble, CMB, OKC, etc.
