Yandex — the so-called “Google of Russia” — has confirmed today that it is launching the social search app Wonder, combining its own proprietary search algorithms with data from social networks like Facebook, Twitter, Instagram and Foursquare, along with voice recognition from Nuance, in an iOS app.

Yandex is launching the app in the U.S. only, and as a “pure experiment” — although it will also be incorporating some of the key technologies in Wonder into more apps soon, and will also be considering how to roll out Wonder itself more widely. “It all depends on user feedback,” a company spokesperson tells TechCrunch.
