From June 1 to June 11, customers who download or update Chick-fil-A's new app, Chick-fil-A One, can get a free chicken sandwich, spicy chicken sandwich or grilled chicken sandwich, according to a Wednesday news release.
The app has mobile ordering, which allows customers to place orders based on their preferences and save those orders for the future.
"Menu items may be customized via the app, and food is prepared when customers 'check in' at the restaurant on the app. The check-in signals the kitchen to prepare the meal and ensures guests receive fresh food quickly and on their schedule."
Customers can also pay through the app and skip waiting in line.
Once users download the app they have until June 30 to redeem their reward.
But a sandwich isn't the only free item you can get from the app.
When you use the app, saves your choice preferences. Each time you use it again, you get closer to another, preference-based reward.
