I have been using StreetComplete on Android thanks to a comment here some weeks ago. This is a really great tool, the barrier to contribute is brought to nearly zero.
The only one thing missing for me is a small history of my past contributions. At some point, I made a mistake and entered the wrong information (nothing terrible, the surface of a walkway, it was 30% one surface, 70% another, I gave the 30% value instead of what I think 70% would be better). I would have been glad to be able to quickly "revert" this contribution.
You can actually split the road into multiple segments and answer each separately if you don't mind the extra effort. I think there should be something like "differs along the way" button which then asks you to pick a point where to cut.

But else, a really great tool.
