Let’s get app-y! Shake Shack® is proud to announce the first-ever mobile ordering Shack App for iOS is now available nationwide. To celebrate the occasion, Shake Shack gave away a free single ShackBurger® to each guest who downloaded the new Shack App from Monday, January 23rd to Tuesday, February 28th, 2017.

To get a free ShackBurger, guests simply needed to download the Shack App, create an account and use the promo code “shackappy” at checkout.

We couldn’t be app-ier about the reception of the “shackappy” promo. We gave away nearly 90,000 free burgers to Shack fans who gave the Shack App a try! We’re so thankful for all the love. For more deets, head to shakeshack.com/app/.

“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. “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.”

The app was developed to elevate the in-Shack guest experience, resulting in shorter pick up times and convenient mobile ordering. Guests can now order Shake Shack when they want it and right from their phone. With the new Shack App, guests can pick their food, choose an available pickup time and it will be cooked-to-order and timed to their arrival. All pickup times are in fifteen minute increments. Check the app for availability throughout the day. More power to ya.

The Shack App features the Shack classics–all-natural beef burgers, flat-top dogs, chicken, frozen custard, crinkle cut fries and more–and includes all of the mobile ordering essentials: guests can find Shacks via a location finder; pick from their favorite orders; keep track of food allergies; access nutritional information; see the latest events and promos; connect to all Shake Shack social media channels and share feedback. What’s more? At any time, guests can view the live Shack Cam at the O.G. Shack in New York City’s Madison Square Park.

The Shack App was created in collaboration with several key partners including mobile product agency Fuzz, mobile ordering platform Olo, guest engagement platform Paytronix and digital experience testing services from Applause. An Android version of the app is in development.
