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 discovered the app a few weeks ago and man, am I thrilled. I totally grinded it out too. Above all, I find the function for measuring the width of the street very elegant
