You can add or remove photos, add introductory text, tweak your stats, and add hobbies and interests.
You can tap the buttons to like or dislike, or swipe right to like and swipe left to dislike, just like other dating apps. Now you'll see all the details along with other photos. You can tap the Heart button to like the profile or the X to dislike, but if you want more information before making a decision, tap the photo. The central part of the page is the photo of your possible match.
The Facebook Dating home page is where you like or dislike other profiles and access your matches.
