An app for Columbia’s African-American Heritage Trail is available free. It is on OtoCast. The app has text, audio, photographs and a map to each of the 22 stops on the trail.

The trail markers highlight people, places and activities from J.W. Blind Boone’s house and music to a movie theater that doubled as a lounge at night.

Note, the app also offers tours to Columbia’s public art as well as one of Columbia’s African-American Heritage Trail.
