Whether you’re going to Burning Man, or just interested, iBurn 2010 is your guide to all the art, camps, and events in Burning Rock City. iBurn 2010 is also open source and totally free.
The app is built to be used offline, within BRC. When you first turn it on, it will cache maps and info about Burning Man to your device. It will also cache any webpages you view via the app.
