Chick-Fil-A is currently running a "Breakfast on Us" promotion at select Dallas-Fort Worth stores, and it's what it sounds like: A free breakfast of either their chicken biscuit or Chick-n-Minis (3-count).

You can't just walk in and demand free food, though. You'll need to make a reservation, with the catch being that you have to make said reservation through Chick-Fil-A's smartphone app. You also have to hand over your e-mail address to make a Chick-Fil-A account.

Making the reservation is pretty simple. When you start up the app and allow it to find your location, the "Breakfast on Us" promotion should be easy to find. Then you just pick a qualifying location, a date (between now and April 25, generally speaking) and a time (between 6:30 a.m. and 10:30 a.m., depending on what's available). When it's time for your reservation, the app will give you a QR code that you can show when getting your free breakfast.

I'm not a morning person, so my wife will have to drag me out of bed for our reservation tomorrow morning, but I like Chick-n-Minis enough that it should be worth it.

You can find more information at Chick-Fil-A's website.
