Whether you love the backpacking lifestyle, or you simply want to meet some like-minded travelers on the road, the recently launched Backpackr app might be your new best friend. The app is part social networking, part travel inspiration. Here’s how it works: Backpackr lets you set up a virtual passport, mark your upcoming trips, and browse profiles of other travelers. Plus, there are also forums where you can post questions, write reviews, offer recommendations or organize get-togethers with new-found friends. You’ll never have to travel alone again.
