The app is made specifically for casual contributors and beginners as no prior knowledge about OpenStreetMap (such as tagging schemes) is required to contribute with this app. Furthermore, there is a bit of gamification and statistics that aim to introduce and try to inspire users to venture deeper into the world of OpenStreetMap.
This app finds missing map data in your vicinity and displays it on a map as quests. Solve each quest by visiting the location on-site and answering a simple question to update the map.
The info you enter is directly added to OpenStreetMap in your name, without the need to use another editor. OpenStreetMap is a really valuable free resource that anyone can contribute to, and which numerous mobile apps also use for their navigation. It is the Wikipedia of Mapping!
The app is open source and is available both on the Google app store but also on the F-Droid store.
