If you’re dashing through one of the two major Houston airports to catch a connecting flight and you’ve got no idea where to head next, rest assured—there’s an app for that. And it’s free.

The app, dubbed “Maps Online,” serves up turn-by-turn directions inside George Bush Intercontinental Airport (IAH) and William P. Hobby Airport (HOU). According to a recent story in the Houston Business Journal, the wayfinding tool resides on the Fly2Houston.com website and does not require users to download a separate piece of software. 

The technology debuted this week and works on mobile, laptop, and tablet devices.

Specifically, once users input a destination, the new app offers both graphical and text directions, along with step-by-step instructions of where to head next and estimated travel times. If you log on from a mobile device, the estimated travel times will update in real time, depending on your pace. 

The HBJ story adds that a search feature will help users locate certain points of interest, including individual gates, places to catch ground transportation, ticket kiosks, and security checkpoints.

Put simply, the app will function like Google or Apple Maps, only inside the airport. The technology isn’t made by one of those big tech companies; instead, it’s the brainchild of a Bay Area–based startup named LocusLabs. The company specializes in indoor wayfinding tools. Houston airports are the first worldwide to offer this iteration.

A LocusLabs press release about the new app notes that at some point in the near future, airport shops and restaurants can offer exclusive location-based deals through the app—a marketing opportunity that could save travelers money so long as they remember to tell servers or cashiers that they found the deal through the app. 

Ultimately, at least judging from how LocusLabs is promoting the technology, this location-based marketing is the primary push. For those of us who are prone to getting lost, a wayfinding app can only make airport time easier.
