From the time it first debuted as part of Google Maps, Street View has been one of the mapping world's most interesting features. Now it's got an app of its own. The aptly-named Google Street View lets you explore the world one 360-degree view at a time. It offers a map view for finding places by location, a Gallery for exploring the most popular places on Earth, and even lets you create your own panoramas, either using the camera on your phone, or in a single click with a connected spherical camera. You can then upload your captures to Google Maps, or store them in a Private section of the app for discreet viewing.
