Keypad-Mapper 3 makes it easy for you to record the GPS coordinates of house
numbers for adding them later to OpenStreetMap.
Features:
* records house numbers
* saves address data
* takes GPS photos for entering in JOSM
* indicates the GPS reception strength of GPS and GLONASS
* exports the recorded information
Note that although it's not mentioned anywhere except very deep in the help
page, this application collects and uploads GSM cell data. See
here for more
information.
Anti-Features: Tracking: The application tracks and reports your activity to somewhere – usually either without your consent, or by default (i.e. you’d have to actively disable it). It’s commonly used for when developers obtain crash logs without the user’s consent, or when an app is useless without some kind of authentication.
