Seconded on Tinder. One of best relationships I had was through there. I like to think meeting people in person first is better but the reality is that the times have changed.
That said, be prepared to wade through a lot of bad fish before finding even a single keeper... especially people looking for more than a hookup. And especially, too, if you're a man. The entire scene favors women heavily, just like IRL. But if you want to put yourself out there then dating apps are a good tool to find some pretty people.
