Buycott is a free app that lets you organize your consumer spending to help causes that you care for, and to oppose those that you don’t.

To use, you simply scan a barcode with the Buycott app and it will attempt to identify the product and determine which company ultimately owns it. Buycott traces the product’s ownership back to its top parent company and cross-checks this company against the campaigns that you’ve joined before telling you whether it found a conflict.’

Campaigns in the Buycott app have a goal and a list of companies that it aims to either support or avoid. Users can search for campaigns organized around goals that they share and also create custom campaigns.

Current campaign examples:

• Vegan and Cruelty-Free
• Avoid Koch Industries
• Avoid George Soros Investments
• Support Prop 37 (The California Right to Know Genetically Engineered Food Act) Donors
