You have your choice of a Chick-fil-A Chicken Biscuit, Egg White Grill, or Hash Brown Scramble Bowl, free of charge. If you order a beverage, side or anything else off of the breakfast menu, then that’s on you. You’re only allowed one freebie during the promotion.
By using the app, you get to bypass the lines and also build up points that can translate into more free stuff. There are also occasional deals that are available exclusively to app customers – like free breakfast!
