Here's How To Get Free Burgers From Shake Shack

Shake Shack is one of the last fast-food chains to launch an app, but we don't mind the wait because it comes with free burgers! Every user that downloads the app gets one free Single ShackBurger to celebrate the occasion.

"The Shack App brings a whole new way to experience Shake Shack for our guests—meeting them where they are, when they want, on their terms," said Randy Garutti, CEO of Shake Shack, in a statement. "Our initial test and rollout have gone very smoothly, and I am thrilled to share that you can now order ahead at nearly all of our U.S. Shacks."

All you have to do is create an account and use the promo code "shackappy." The deal is good from now until Feb. 28, so there's plenty of time to cash in on free beef. After that, you can use the app to order ahead and cut down on wait time.
