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.
An alternative for iOS is “Go Map!!”.
Thank you!
Also like that the iOS app privacy section says:
Data Not Collected The developer does not collect any data from this app
You don’t see that every day!
Unfortunately, it’s not available in my country :/
