Nearby Explorer Online is a free outdoor and indoor location app designed for use by people who are blind. It supports onboard maps from OpenStreetMap and can optionally augment these maps with online data from Google Places.
The app works by letting you select from different location related options about what to announce as you move. These include typical items like street name address and nearby places as well as the distance and direction to them. (All announcements are optional.) All of this information is shown on the main screen and is available at any time but typical use is to adjust the level of announcements then lock the screen and put the device away. This keeps both hands free and lets your preferred voice speak the characteristics of the environment as you move.
You may also use the devices position and orientation to obtain additional targeted details such as pointing the end of the device to scan for points of interest or tilting it vertically to function as a compass. You may even mark a point then use the position of the device to get haptic feedback about that point's location.
You may also create favorites name them and share them on OpenStreetMap so others can benefit from the places you mark and identify.
A transit feature is included which provides detailed mass transit schedules for over 100 metropolitan areas in the U. S. and Canada. The app treats transit stops just like favorites and points of interest by announcing their name and relative position as you move but in addition transit stops add next vehicle stop time direction of travel and route name to the announcements. You can use the transit schedules to look up times or even follow a route.
You may virtually move to any area and explore search or use the transit maps for that area.
