Here's How to Get a Free Burger from Shake Shack

Shake Shack has joined the world of mobile ordering and that means free burgers for everyone! The app actually launched a few months ago and allowed users to download, order, decide a pickup time and show up for lunch. No waiting involved. The one piece of information that not everyone knew was that once you download the app and place your order, you can use a secret code to get a free burger from Shake Shack.

After you've created an account and use the promo code Shackappy at checkout. As of this week, NYC Shack fans were loving their free burger. "I thought that promo was over! Free lunch!" said Tevi, an intern at a nearby startup.

"The Shack App marks a new era for Shake Shack. In creating our first-ever app, we took great care to develop a mobile ordering platform that maintains the high quality our guests have come to know and love, but now just a tap away," said Randy Garutti, CEO of Shake Shack.

"We're meeting people where they are and giving our guests a whole new way to experience Shake Shack. We've got a lot to learn, and we intend to take our time listening to our guests and tweaking the app before launching it in additional markets."

Baby, you're so classic. ?: @pdxdining. #shakeshack #shackburger
