StreetComplete is an Android app developed by westnordost, available for free in the Travel & Navigation category. The app aims to improve the OpenStreetMap by finding incomplete and extendable data in your vicinity and displaying it on a map as markers.

The app is incredibly easy to use. Simply click on a marker, answer a simple question to complete the info on site, and the info you enter is then directly added to the OpenStreetMap in your name. This means you can help to improve the OpenStreetMap without the need to use another editor or have any experience with mapping.

StreetComplete is a fantastic way to contribute to the OpenStreetMap, while also exploring new areas and learning about the world around you. The app is updated regularly and is constantly adding new markers to the map, so there is always something new to discover and contribute to.
