Wow, thanks for mentioning https://streetcomplete.app! This looks very intuitive to use for edits on openstreetmaps.

Would someone here know a similiar tool for iOS or MacOS? Or any recommendations to edit roads.

We are currently driving with a 4.5 tonne motorhome in Europe and the road weight and height limits are usually marked properly in osmand+ but when they are not we waste multiple hours rerouting in the alps and I would really want to help the next person in similar situation.
