More than 1 million customers have joined Chick-fil-A One, the restaurant company’s new app that allows guests to customize their order, pay in advance, and skip the line at the register. The surge quickly boosted Chick-fil-A One to the No. 1 spot in the iTunes App Store only a few hours after the app was announced on June 1. It remains in the top position for free apps for the third day in a row, with six registrations taking place every second. Chick-fil-A One has also been installed on more than 450,000 Android devices since the launch.

“The app was developed based on customer feedback, so it’s especially rewarding to see the interest around Chick-fil-A One,” says Michael Lage, senior manager of digital experience for Chick-fil-A.

To thank guests, any customer who downloads (or updates) the free app and creates a Chick-fil-A One account between now and June 11 will receive an offer for a free Chick-fil-A Chicken Sandwich, Spicy Chicken Sandwich, or Grilled Chicken Sandwich. Once the offer is claimed, guests will have until June 30 to redeem their free sandwich. As of June 2, 131,000 free sandwiches had been redeemed.

Chick-fil-A One, which replaces the restaurant chain’s previous app, features a unique membership program that will surprise customers with their favorite food for free, based on their preferences and previous orders. As users order or purchase through Chick-fil-A One, they get closer to their next free offering and can track their progress in the app.

Chick-fil-A One is available via the Apple App Store or Google Play, or simply by tweeting through an activation that was custom-built by Twitter for Chick-fil-A. From June 1 through August 14, customers can Tweet #CFAOne with the horizontal cow emoji to receive a prompt to download the app from Twitter directly to their mobile device. Membership is open to anyone over the age of 13.

Chick-fil-A launched the first version of its app in 2012. The company began piloting mobile ordering in 2013. All Chick-fil-A One users also have full access to the app’s other features, including nutrition and allergen information and a restaurant locator.
