Targeted at Makers, Rubble allows users to upload a picture and description of reusable materials. The app automatically geolocates and time stamps the find.

Users can also search for materials by category and area. When a user finds a post that they like on the app, they click the heart icon and the post is automatically uploaded to their ‘Favourites’ section. As the user approaches the area where the find is located, the app prompts them to verify whether they have taken all, part or none of the materials.
