Sons Of Smokey - SOS app is a free iPhone application developed by Sons of Smokey. It aims to connect public land users and volunteers interested in restoring public land for future generations. The app allows users to identify and clean illegal dump locations on public land by geotagging and photographing abandoned vehicles and dump sites. The real-time map feature keeps track of these locations.

Users can scout marked locations for clean-up projects and mark them as cleaned up once the task is completed. To use the app, users need to download it, create an account, and open it while on public lands. If they come across dumped debris, they can double-tap the area on the map, leave a description, and take a picture. The app displays a trash icon for easy identification and updating of locations.
