Go Get A Free Burger From Shake Shack, Today!

Want a free burger from Shake Shack? Of course you do. All you have to do is download the app!

Business Insider reports that the burger chain is gifting a single ShackBurger to anyone who downloads the app, which has just been made available in all 50 states. This is both an act of celebration, and a way to encourage customers to get familiar with the newly launched app software.

The app is called "Shack App," and to cash-in on your free burger, you can use the promo code "shackappy" upon checkout. The best part is that it's redeemable at any Shake Shack location (other than those in airports, stadiums and ballparks) anytime until Feb. 28, 2017.

Shake Shack is known for having exhaustingly long lines, and this new ability to order online allows customers to skip right over all of that waiting. According to Eater, the app is currently only available on iOS, but there are rumors that an Android version is in the making.

The app itself allows you to order any of your favorite menu items, and even allows you to customize them as well. The only menu item that appears to be unavailable is the frozen custard line, but you can still get the chain's dog treats and custom-made candy bar.

Testing the app had been going on since October 2016 at one location in Midtown Manhattan, New York City. The process involved ordering and paying for menu items, and then receiving a text when those ordered items were ready. Then, the customers can drop by and pick up their items in a designated to-go area of the restaurant. It's no surprise that such a convenient style of food ordering passed the testing phase and has picked up (since other chains are already using it, such as Taco Bell, Starbucks and Chipotle) in popularity. How much faster and easier can fast food get?

Just take a look at the sleek design of the Shake Shack app, and tell me it doesn't look easy to use. Great job, Shake Shack!
