StreetComplete is an application allowing to contribute to OSM by answering simple question. It makes possible to contribute without learning about tagging schemes and without learning how to handle interface of more general editor like JOSM, iD or Vespucci.
I contributed to StreetComplete in past. Recently I received a grant that will allow me to spend more time on improving it.
Grant is funded by a NLnet as part of NGI Zero grants. StretComplete grant is mentioned by NLnet at https://nlnet.nl/thema/NGIZeroDiscovery.html and https://nlnet.nl/project/StreetComplete/ pages. It will allow me to spend far more time on improving StreetComplete.
I will participate in project as usual, sending pull requests that will be reviewed and accepted (or rejected) by StreetComplete author, Tobias Zwick.
Note that I selected topics of work to be done (based mostly on open issues on the bug tracker) and that Tobias who will review pull requests remains completely independent - I am sole beneficiary of the grant.
