Guide Dots is a free audio-based app that gives greater independence to the visually impaired. A perfect complement to a guide dog or cane, this app uses audio prompts, Facebook Places and Google Maps to call out places as people pass. And with the ability to tag route details and find nearby friends, Guide Dots is a walking guide to any city in the world.
With a growing Guide Dots community, users can create detailed databases of localized information. From hazards in the walkway to the location of a restroom in a store, the information grows with the community, creating a completely crowd-sourced map of the world.
