Looking for the next big “app” for your iPhone or Android phone? CauseWorld lets you donate to charities of your choice, including Carbonfund.org, for free while you shop! CauseWorld enables users to accumulate “karmas” when visiting various stores which can then be used for donations. No purchase is required. The mobile phone application is free to download and use via Apple iTunes here or via the Android Market on one’s phone. With grants from Citi and Kraft, CauseWorld is able to distribute funds to the charities that users select. The updated app includes a social layer, meaning you can now sync it up with Facebook to share your experiences and donations you’re making with friends. Also, Procter & Gamble (P&G) is sponsoring a way for users to earn extra karma points by scanning barcodes on individual items with one’s iPhone. The app helps connect users with products they may be interested in, while earning karmas that they can then use for donations. The app has been lauded by TechCrunch, featured in the San Francisco Chronicle, and was recently highlighted at the popular South by Southwest (SXSW) conference and festival in Austin, Tex. There, TechCrunch and CauseWorld teamed up to offer attendees double karmas when one checked in with the app at any of over 50 venues around the city including the Austin Convention Center.
