In order to get your free burger all you have to do is show that you are an active Whataburger Rewards member at a participating Whataburger.
If you haven't joined, you can download the Whataburger app and sign up for a free Whataburger Rewards account. You also have to place at least one order on the app to be considered an active user.
Whataburger said that so many people tried to get on the app at lunchtime that it crashed.
Whataburger is also celebrating by relieving $73,000 of school lunch debt for children across the country, with their parament All for Lunch.
Poll finds Texans love Whataburger, dislike Jerry Jones
A new poll finds that Texans are in love with favorites like Whataburger and H-E-B, but have an unfavorable view of Dallas Cowboys owner Jerry Jones.
The chain is also giving away limited number of inaugural National Whataburger Day table tents for people who go inside the restaurant.
The first Whataburger was opened in Corpus Christi by founder Harmon Dobson in 1950.
