That is a great initiative! I just installed the app and contributed some tweaks in my area.

Also, I couldn't find any info on this matter: some quests ask you what number a house is. Wouldn't people find it strange that a random person is standing in front of your house and looking at the number and then types on their smartphone?

AFAIK house numbers are not private info, but still...

Happens to me regularly, especially when I take photos of shop names, opening hour or draw building outlines (on an existing OSM map printout). The more residential the area the more questions. Of the last five questions two knew what OpenStreetMap is so that's progress.

I usually carry a few stickers on me just in case, so people can remember OSM and look it up later (after I explain what I'm doing and say it's a fun community project).

you can just apologise for the inconvenience and move on if anything happens, it's not like they can call the police or anything

> it's not like they can call the police or anything

Well, they can. Whether or not the police will bother doing anything can depend on a lot of factors.

Anything like this for iPhone?

I use OSMAnd and Go Map!! to make edits.

Go Map!! is particularly good for editing, while OSMAnd is a more full-featured map application which also supports editing.

Yeah, I love OSMAnd for that reason. With it, you can add POIs and for more complicated edits that need a bigger screen etc. it's easy to add OSM Notes (which other mappers can then follow up on). Notes I find particularly good when I'm travelling and don't have time or enough knowledge of the area to actually edit the map, but want to help others do so.

Go Map! is indeed a fine app. But it does require some OSM knowledge, like the various tags. In that regard the linked Android app is a lot simpler.

Not for contributing/editing, but for an offline map set with CarPlay, I use Magic Earth.

The routing algorithms are okay though.

Agree! Can't be easier than this!
