Having Yelp in your pocket is like being able to ask the locals where to stay, eat, drink, and shop. This location-aware app provides user reviews for a wide range of businesses, which it quickly pinpoints on your smart phone’s map. The most robust version is the iPhone app. Its unique Monocle augmented reality feature lets you see how many stars that bistro got just by pointing your device’s camera in its direction. You can also “check in” to businesses—foursquare-style—to broadcast your whereabouts to friends on Facebook, Twitter, or Yelp.
