"Chick-fil-A One, which replaces the restaurant chain’s previous app, features a unique membership program that will surprise customers with their favorite food for free, based on their preferences and previous orders," the company explained in a press release. "As users order or purchase through Chick-fil-A One, they get closer to their next free offering and can track their progress in the app."
Speaking of free food, Chick-fil-A said it will give you a free chicken sandwich just for downloading (or updating) the app and creating a Chick-fil-A One account between June 1st and June 11th. Specifically, you'll receive an offer for either a free chicken sandwich, spicy chicken sandwich, or grilled chicken sandwich, which you'll be able to redeem through June 30th, according to the press release. We tried it out and it's as simple as it sounds.
