Facebook dating is not a separate app, but it is built right into the Facebook site if you already have a Facebook account. The only difference is that you will need to open a separate dating profile.
All you need to do is go to the Facebook app, click on the menu icon on the upper side of the screen and then select dating. This will direct you to the Facebook dating section.
Click on “Get started” for setting up your profile. You will need to specify your gender, location, and also choose a nice photo for yourself.
After you complete that, Facebook will generate your dating profile quickly. Also, you can edit your profile the way you want by adding a photo. You can post and also removing things when done and satisfied tap on “done.”
