No iOS version as the other comment mentioned, but if you want to contribute, try Every Door ( https://every-door.app/ ) for now.
It doesn't have points and badges like Street Complete, but you can easily add/update/fix amenities, update addresses, add info about buildings, and fill in the same data using the "micromapping mode". I started with Street Complete, but now use this for most things.
