Match is a big step-up from casual dating sites, using an in-depth questionnaire to find you the ideal partner.
Facebook and Twitter are, of course, most popular social networks, and you've probably already downloaded them.
Each has millions of members and full-fledged apps you can download on i OS and Android.
Tinder's the biggest thing to shake up online dating since "You Got Mail." It damn near invented the idea of right-swiping for "yes" and has evolved from its original "hookups-only" origin to a more standard dating app.
The original dating app was once the place for social introverts to meet their significant other.
Now it’s a tool for swiftly finding an insignificant one-night stand - whether you're straight, gay, bi, transgender or gender-fluid.
