Shake Shack announce the first-ever mobile ordering Shack App for iOS nationwide and to celebrate the occasion, Shake Shack is giving away a free single ShackBurger to each guest who downloads the new Shack App. The offer is redeemable at any U.S. Shack (except airports, stadiums and ballparks) until Tuesday, February 28th, 2019.
To get a free ShackBurger, guests simply need to download the Shack App, create an account and use the promo code “shackappy” at checkout. For more details, head to shakeshack.com/app.
Sadly there’s no such offer for Androids, but with the money I saved on my LG phone, I can buy tons of burgers.
