This app turns your phone or smartwatch into a sonar that detects and displays nearby locations.
Just define the locations you wish to track using their geographical coordinates and adjust the detection radius accordingly. Sonar will only detect these locations within the desired radius. Each detected location will appear as a sonar point whose position indicates the distance and angle to the location. The distance is also displayed in the list of locations to help you better adjust the detection radius.
The app requires GPS data from either the watch or the phone to detect and display locations.
