Facebook Dating enters the dating-service market years after competitors like Tinder and Bumble, but it starts with a huge advantage: Most people already have Facebook accounts. And while Dating works only on mobile right now, it doesn’t require downloading an additional application to your phone.
use the service's Secret Crush feature in which you can select up to nine Facebook friends or Instagram followers you have an interest in. If they also express an interest in you via Secret Crush, Facebook will match you up.

You're currently able to add Instagram posts to your Facebook Dating profile as well as share Facebook and Instagram stories.

Dating apps like Hinge have historically marketed themselves on their ability to match you with friends of friends—people with whom you already have existing social ties. Facebook Dating also allows you to do the opposite: You can preemptively turn off matching with friends of friends, which may be a welcome option for anyone who wants to date outside their network. PLUS, enjoy music, memes, funny videos, Daily quote love and more.
Facebook Dating’s most exciting new feature builds upon a well-established safety practice for online dating. Before meeting someone in person for the first time, many people—especially women—tell a friend or family member where they’re going and when they expect to be back, in case something happens. More recently, people have been sharing their location using tools like Apple’s Find My Friends. Facebook will allow you to automatically open Messenger from Dating and tell a friend the name of the person you’re going on a date with, as well as the time and place where you plan to hang out. Fifteen minutes before your date happens, that person will receive a notification reminder and access to your live location. But unlike Find My Friends, your location is only shared for up to an hour, at least for now.
