I wish Streetcomplete had an ios app. The ios editors are all far too cluttered and hard to use on mobile. I've almost been considering making my own editor like streetcomplete but as a web app so it's cross platform.
The problem is "very powerful" is the opposite of what I want in a mobile editor. I've tried some of the existing options but they are just not ergonomic to use. I want to fill in missing details with an easy to use spacious UI, not have a fully functional GIS mapping tool squished on to a phone screen while I'm standing on a busy street with sun glare on the screen.
