Yelp has snuck the first Augmented Reality (AR) iPhone app specifically for the US into the iTunes App Store. The undisclosed new feature allows iPhone 3Gs owners to shake their phones three times to turn on a view called "the Monocle." This view uses the phone's GPS and compass to display markers for restaurants, bars and other nearby businesses on top of the camera's view.Social review service
Blogger Robert Scoble discovered the hidden feature and posted about it on FriendFeed today. A screenshot is below.

Developers did not expect to be able to get Augmented Reality apps into the App Store until the release of the next iPhone OS this fall. Earlier this week, though, we reported on what appeared to be the very first - an update to an app called Metro Paris Subway.
Layar and Wikitude, two European companies offering multi-purpose AR browsers, both have Android AR apps that include content for the United States, but neither company has released an iPhone app yet. Layar's CEO said yesterday that he was testing an iPhone version of his company's software and that it was "very fast."
Building a little AR into an already established app seems to be the method of choice for sneaking AR into the app store.
This may be what the future of mobile Augmented Reality looks like: many vendors offering their own in-app AR views, and a handful of AR browsers like Layar, Wikitude and Acrossair aggregating many different published AR views or layers.
