The first one I tried was Doulike. I liked the way it pulls conversation starters from your info to help break the ice. I went on a couple of decent dates through the app.
Next up was Bumble, where women had to make the first move by sending the opening line. I thought that was an empowering concept, but in practice, it meant a lot of my matches just expired before I could work up the nerve to reach out. The free version was pretty limited on there as well.
Then a work friend told me about OkCupid - she raved about how in-depth the questions and profiles were to help find compatible matches. I tried it out and immediately loved the ability to really get to know people beyond just some photos. I went on quite a few stellar dates with people I clicked with personality-wise right off the bat. And the best part? I could message matches for free.
