It’s not exactly the same, but I can vouch for StreetComplete being an incredibly good/similar game. You walk around the real world, and the app points out missing data in OpenStreetMap that you can fill in easily. You get the dopamine of a number going up, help dethrone proprietary map dominamce, and get some good excercise in in the process.
StreetComplete is Android only, but last I heard Go Map!! for iOS was trying to add a similar “quest” functionality to that found in SC.
