Shake Shack is giving away a free single ShackBurger to guests who download the Shack App for iOS, create an account and use the promo code “shackappy” at checkout. The app was developed to elevate the in-Shack guest experience, which results in shorter pick up times and convenient mobile ordering. With the new Shack App, guests can pick their food and choose an available pickup time; it will be cooked-to-order and timed to their arrival. All pickup times are in fifteen minute increments. The free burger offer is redeemable at any U.S. Shack except airports, stadiums and ballparks until Feb. 28.

The Shack App features classic menu items such as burgers, flat-top hot dogs, chicken, frozen custard, fries and more; it also features mobile ordering essentials like a location finder, nutritional information, events and promotions.
