We'll admit it: we're obsessed with iPhone apps created by magazines. And we don't even have an iPhone! (Blackberry all the way.)

Today, we learned of two new magazines entering the market with new apps. Seventeen magazine's Fashion Finder app is the first for a Hearst title, offering its readers the ability to locate clothing and accessories featured in the magazine in stories near them.

Then there is Runner's World's new app, which is sponsored by Nike, called the Runner's World Shoe Shop. The Rodale title's app is actually similar to Seventeen's app. Both are made in partnership with NearbyNow, a digital shopping concierge service that allows users to search for products in locations close to them.

Additionally, the Runner's World app, which is available as a free download, offers users access to reviews from the RW Shoe Lab and shoe-buying advice, Rodale said.

Although these apps are all pretty cool and helpful, we're wondering if they'll help earn their related magazines any extra money, especially if their publishers are just giving them away for free.
