"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."
It's good, but it depends on the map having the details in the first place. e.g. near me, the roads are mapped, and a lot of the town centre, but there's a huge amount missing.
Street Complete can't ask about a building if it hasn't been added to OpenStreetMap in the first place.
I thought the filter was to only complete quests for certain objects. I had no idea that you could add items too. That's going to make things easier for me :)
I've used it quite extensivly, big fan. It asks for further details on objects that have already been mapped, which also reveals things that don't exist anymore. It turns mapping into a really fun game with currently 163 different quests. The app also regularly asks you to verify opening hours or confirm the existence of certain objects.
That being said, I almost always use it in conjunction with a real map editor, to add new stuff I find or to make more complex edits.
I've used it quite a bit recently. It makes it really easy to submit data in small amounts. I usually have it open while walking my dog and enter in basic things as I go. I've completed about 1500 quests so far with it.
