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.
