Help to improve the OpenStreetMap with StreetComplete!
This app finds incomplete and extendable data in your vicinity and displays it on a map as markers. Each of those is solvable by answering a simple question to complete the info on site.
The info you enter is then directly added to the OpenStreetMap in your name, without the need to use another editor.
I have it installed, but miss some minor features. Swipe left to delete, to begin with. Hold to move cursor. Such small quality of life features. Or am I missing them?
