I never used dating apps, it always seemed like a ridiculous waste of time, at least for men. But as I am semi-introverted and don't drink, I also had no idea where to meet people. One day I found meetin.org, which was a very active community 15 years ago (today not so much, but meetup.com is somewhat similar). Through meetin.org I attended a Salsa class with other members, then started taking other salsa classes on my own and eventually found my wife at a party when my dance teacher introduced me to her. I think the key is just to a) get out and b) male-dominated places don't count.
