Online road service directory Inc. has rolled out a new iPhone app to help truckers and RVers locate the nearest service providers on the road.

This app has access to more than 25,000 service locations throughout the United States and Canada. Service providers are added and updated daily, so live access with the app ensures the latest providers are included in every search a user performs.

The road service app allows users to select from six categories: towing, road service, truck repair, tire repair, truck stops and truck scales. Once a category is selected, with just a few clicks, users are able to locate the nearest service providers from their location, by selecting the nearest known city, nearest zip code or entering GPS coordinates.

This app is a complementary addition to the search tools already provided by 4RoadService, which includes the original website as well as the mobile site for use with all other mobile devices with an Internet connection.

The app can be downloaded free of charge from Apple's app store using an iPhone or by visiting the website. Inc. has been operating a free, online road service directory since 2004.
