MapTogether is an application meant for making contributing to OpenStreetMap a more user-friendly experience. It is inspired by and in many ways similar to the fantastic StreetComplete, but developed from scratch in different technologies.

The application is comprised of a client in Flutter which can do all mapping activities on its own, a social server written in Crystal, two libraries for interfacing with OpenStreetMap and MapTogether APIs written in Dart. This is all organised in a mono-repository on GitHub for atomic updates across the many codebases.
