In Short

Tango — originally dubbed Project Tango — is a technology platform from Google that allows developers to create experiences that incorporate things like indoor navigation, 3D mapping, and augmented reality. Tango uses computer vision toe enable devices to see the world around them without relying on GPS. Two devices used to demonstrate Project Tango have been the discontinued Peanut phone, and the 7-inch Yellowstone tablet.

Unlike other devices — including VR accessories — Project Tango allows is designed to run on a standalone phone or tablet. This works by integrating motion-tracking (using the accelerometer and gyroscope), area learning and depth perception.

During CES 2016, it was announced that Google would be working with Lenovo to bring a smartphone with Project Tango technology to market. On June 9, 2016, The Lenovo PHAB 2 Pro smartphone was announced during Lenovo's Tech World keynote. The PHAB 2 Pro will be the first consumer smartphone with Google's Tango technology, using the built-in 3D camera to sense and map out its surroundings. The phone will be available for sale at Lowe's and Best Buy stores at the end of the summer for $499.
