Shoparoo (free)

Back to school time is often a great opportunity for brands and parents to help raise money for local schools, and Shoparoo makes things easier with a new app that converts your store receipts into school donations. In turn, you earn exclusive rewards, bonuses and coupons. There are no restrictions on the types of products you can purchase, or the stores from which you shop, but donations will be doubled if you purchase a featured brand. To donate, take a photo of your receipt from your Android device camera and submit. Select the school or charity of your choice and help your local community raise funds.
