Chirp AR

Chirp AR is a free app helping the blind community better understand their immediate environment through echolocation, distance detection and color recognition.

Detect objects in your environment (including their distance and color) through audio and verbal feedback using just the iPhone's camera.

Developed with help from the American Printing House for the Blind and Kentucky School for the Blind comes an app using just the camera to detect distance and echolocation for the visually impaired.

"This app has potential. You could consider it the audio equivalent of a tactile sensory feedback tool."
