Notes App: Existing Apps that show or add OSM Notes

In order to make the best Notes app possible I’d like to understand what apps are out there that enable adding (or viewing) of OSM Notes. This is so that we can learn from existing apps, understanding what works well, and what we can try to improve upon.
So.. __... here’s a thread to add Apps to. Please feel free to add apps that use or show OSM Notes. If possible, please make a note of as many of these as you can:
* the name of the app
* the platform (e.g. iOS / Android / WebApp)
* screenshot(s)
* a link to the app on it’s relevant store.
* anything that is especially awesome about the app
* anything that could be improved about the app.

- Maps.Me allows you to add notes.
- Not sure but perhaps StreetComplete shows Notes.
- It doesn't do Notes but I want to flag OSMFocus as it's a great little app :-D

Great, thanks Rob!
I've tried to find where Notes are within Maps.me and so far failed - do you know where it is? I wonder if they've changed or removed the feature in the current version.
What do you particularly like about OSMFocus?
