GoodGuide is your guide to all things that are good for you and good for the environment. The guide is available on the web and in a pocketable version that you can carry on your iPhone.
The GoodGuide app for iOS contains ratings for over 210,000 products in a variety of categories, including food, health and beauty aids, pet food, baby care and more. Each item is rated on a scale of 1 to 10 based on its social, health and environmental impact. You can quickly view an item's overall rating as well as detailed ratings for health, safety and environment.
One of the most useful features of GoodGuide is its scanner tool that allows you to scan product barcodes to find out more about the items that you are about to purchase. The app lists information about the brand that makes the product, its ingredients and alternative products that you may be interested in buying.
GoodGuide's biggest drawback is that its product catalog includes only those items that are commercially available in the US. You can use the app outside the US, but the product information will be limited to those items that are available in the US.
GoodGuide is available for free and is compatible with the iPhone. It requires iOS 7.
