In-N-Out Burger Sparks Long Lines in Tennessee, App Launches to Help

The arrival of In-N-Out Burger in Tennessee has led to unprecedented demand, prompting the launch of a new app designed to help customers manage lengthy wait times. The popular California-based chain opened its first three locations in Lebanon, Antioch, and Murfreesboro in mid-December 2025, drawing massive crowds and creating hours-long lines.

To address the overwhelming demand, a web-based platform called Thewaitapp.com was introduced to provide real-time updates on wait times for both in-store orders and drive-thru service. According to local news outlet WSMV, the app relies on crowdsourced data, allowing users to share their experiences and keep wait time information current.

In-N-Out’s rapid expansion into Tennessee occurred within a week. On December 10, the first two locations launched in Lebanon and Antioch, leading to immediate multi-hour lines. A third location opened on December 12 in Murfreesboro, further increasing the brand’s presence in the region. Shortly after these openings, The Wait App was launched to assist customers in navigating the long lines.

This expansion is significant for Tennessee residents, marking the cultural and economic impact of a beloved fast-food chain. The phenomenon, often referred to as the “In-N-Out effect,” illustrates how brand loyalty can create technological solutions to enhance customer experience. For many diners, using the app can be the difference between a quick meal and a lengthy wait, as it even offers a “confidence level” indicating the reliability of reported times.

Lynsi Snyder, the heiress and CEO of In-N-Out, announced plans for further expansion in Tennessee, including an administrative office in Franklin. Earlier in 2023, Snyder revealed her family’s decision to relocate to Tennessee, citing challenges associated with business and family life in California. She expressed her commitment to providing opportunities for In-N-Out associates in the new territory.

The history of In-N-Out Burger dates back to 1948, when it was founded by Harry and Esther Snyder in Baldwin Park, California, as the first drive-thru hamburger stand in the state. The chain has since grown to operate over 400 locations across several states, including Nevada, Arizona, and Texas.

While initial excitement has begun to settle, long wait times are likely to persist through the holiday season. The success of Thewaitapp.com may establish a model for future In-N-Out expansions, as the brand continues to capture the interest of customers beyond its California roots.
