For Apple devices (iPhone, iPad, iPod Touch) we have a custom app called "Camp Where"  

Camp Where provides detailed information on over 11,500 public campgrounds in the United States and Canada. These include all car-accessible US and Canadian National Parks, National Forests, Corps of Engineers, TVA, BLM, State Parks, State Forests, State Recreation Areas, Canadian Provincial Parks, County and City campgrounds. Camp Where operates on the iPhone, iPad and iPod Touch. Much useful information is accessible even without an Internet connection.

All campgrounds are accurately mapped, providing reliable latitude/longitude and coordinate-based road directions. Camp Where is integrated with the Navigon iPhone App for off-line routing. Most campgrounds have details such as phone numbers, RV hookups, reservations, current and forecasted weather, elevation and more. Web links and phone numbers are provided for further information.

Well over half of all public campgrounds DO NOT accept reservations – Camp Where is the only app that tells you which do and which don’t and provides a reservation phone number and direct link to the appropriate reservation web site.

See Camp Where on the BackPacker magazine web site.

Camp Where does not include privately owned campgrounds or backpaker campgrounds. There is no Android or Windows Phone version yet..
