Fans attending Detroit Lions games at Ford Field can use an innovative new feature in the team’s official app to find directions to their seats or locate restrooms, concessions and merchandise vendors.

Pittsburgh-based developer YinzCam, which launched the Lions app in 2012, incorporated Apple Indoor Positioning to help fans navigate the downtown Detroit venue. The Lions are now the first NFL team to incorporate this feature, which became available for their Thanksgiving day home game against the Minnesota Vikings. The groundwork for this tech was installed during the stadium’s $100 million offseason renovation.

“Before we had our map, we had a lot of fans who would ask simple questions, like ‘Where is the elevator?’ or ‘Where is the restroom?’ But this map has everything layered into it,” Todd Marcy, the Lions’ Director of Digital Operations, said in a press release. “YinzCam’s custom development also provides us with a lot of flexibility, so that we can quickly go in and modify the locations within the map, adding a new concession stand or menu, depending on what type of event is taking place on a particular day.”
