YSK: StreetComplete app for Android, a way to fill map data in a game like way

You fill out "quests" like if sidewalks have tactile ramps (for accessibility), what type of roads, road size, store hours, if bus stops are illuminated or have a shelter, bike spots, etc.

It's been a few days and I'm addicted. And it's a good way to contribute to OpenStreets and reduce supporting commercial map tools like Google Maps/Apple Maps.

I learned about it during a No Stupid Questions post about mobile games that reward you for walking.

I'm still relatively new and on the Global Leaderboard, ranked 1000 out of 5000.
