The GoodGuide app aims to help you find safe, healthy, and sustainable products while you shop. Simply scan a barcode, and the app gives you ratings on that product's health, environment and social responsibility stats. Even though the database has more than 70,000 products and companies in it, I've found that sometimes the app doesn't always scan the product. Still, it's a stellar idea and it'll likely continue to improve.
