Augmented reality is quite a promising field of app development for all smartphone platforms. There is, undoubtedly, a lot of room for improvement when it comes to Windows Phone 7 apps that deal with AR, but recently, some pretty good AR browsers have started making their way into the WP7 Marketplace. We covered Nokia’s City Lens (review) a while back, but that is not the first, or even the best, augmented realty browser out there for Mango phones. That honor falls to Wikitude, an app that has been around in the Marketplace for quite some time, but has become even more awesome thanks to a few really good updates. It is not focused on just letting users discover interesting places near them; you can even use it to find people that have recently tweeted in your vicinity.
