Shake Shack's mobile app now takes orders across the US

You'll be able to order your meals and pay ahead of time.

You might have one more option to choose from if you don't feel like lining up for some fast food. Shake Shack has joined the growing list of food chains with mobile apps that give you a way to order and pay ahead of time. The restaurant has been testing the service in Manhattan for the past few months, but it's now available in multiple locations across the US. Sadly, it's not a full nationwide rollout -- the company left out some locations, including Austin, Dallas and Atlanta. Plus, only the iOS app is available for now, though according to Eater, Shake Shack is also developing an Android application.

If the chain now accepts mobile orders where you are, you'll be able to choose the branch where you want to pick up your grub, as well as the time you'll be dropping in. Most of the items in the resto's menu are available through the app, save for some exceptions like its frozen custard concretes. However, you can only buy four items per category, so if you need a fifth burger, one of your friends has to order the last one.
