Nationwide Insurance debuted Cartopia, an app for the iPhone and iPod Touch that offers vehicle safety, pricing, and payment information to car shoppers.

Nationwide teamed up with Experian Automotive, the Insurance Institute for Highway Safety, and IntelliChoice to provide used-vehicle history scores, trade-in values, and payment calculators. Consumers can even use the app to apply for auto loans or to request insurance quotes.

Another neat feature: Car shoppers can add notes and store multiple pictures of vehicles being considered. They can then rank their choices based on different criteria.

Cartopia is available for download from the iTunes App Store.
