SFMOMA offers fully guided tours of America’s largest contemporary art space. They’re narrated by not one but dozens of international voices. Further, they’re sensitive to your precise location in the museum to keep you on track and give you natural feedback , no matter which piece of art you’re staring at. The best part of this app experience is that it keeps you off your phone; everything is automatic, so you can keep your device in your pocket and enjoy a new tier of seamless experience. Because the app is so responsive to the user’s location, it really is akin to augmented reality. The only difference is, this product uses sound, not visuals.
