I’m curious where you live that there isn’t much mapping data. I’ve used StreetComplete for a few years, everywhere I’ve been wherever I’ve travelled all over the world. Wherever I go, there’s already so much data and it’s already so detailed, that the only stuff StreetComplete can give me is “what kind of paving stones are used on this sidewalk?” and “how many floors are in this apartment building 3 blocks away?”
