How's this compare with street complete? It seems like the categories are different and maybe wider?
just curious how the different tools the community has made stack up
For start StreetComplete is an Android app unavailable (for now) elsewhere.
MapComplete has multiple in-depth layers, while StreetComplete is more general.
StreetComplete puts more focus on being usable out-of the box for newbies, while I would describe MapComplete as having focus on usability but allowing deeper dive in specific topics.
(disclaimer: I helped with developing StreetComplete)
Streetcomplete can filter the map with a variety of filters for features you can edit or complete(Street lighting, Surfaces, Sidewalks, Bike paths, Street parking, Addresses, Places, Things, Buildings). Plus there's some specific "quests" where you can complete information for specific POI ("Does this bench have a backrest? Yes|No", "Where does this fire hydrant lies? On the grass | On the roadway | On a walkway | On a parking).
Mapcomplete also offers filling info about existing POI, but you can filter on specific theme (Drinking water, sports) or very specific theme (etymology) or even your own. There's also an UI to add new POIs; I don't think it's possible with StreetComplete.
Either way both are great.
