Just out of curiosity, how quest-less is your vicinity? Because for the village I live in there's almost nothing left by now and I had to resort to micro-mapping street lights, hedges, fences, walls, trees, entrances, building/roof colors and materials, etc. when outside, instead of using StreetComplete.
(I'm only #263 in Germany and #714 globally, though.)
It's a really great gateway into OSM, I have to admit. Even though my previous work had to do with maps and I've had an OSM account since then, I've never mapped gain after the first few changesets until I found StreetComplete this winter.
I have lived in a lot of different places over the past three years so have improved each area as I pass through. Now where I am settled down most of the city's buildings aren't even traced so there is a lot to do. I'm busy with substantial home improvement projects for probably the rest of the year but I will get to it eventually.
I once added a bench to OSM just to see how the process works, and it all feels pretty tedious, specially when you want to update it in order to add some properties.
There's the Android app OSM Go! nowadays (https://wiki.openstreetmap.org/wiki/Osm_Go!), made by a French developer so it might have some local bias, but it's the easiest app I've seen to add point-based POIs, like trash cans, shops, playgrounds, billboards, etc. It's not perfect (some templates miss optional properties), but it enables adding POIs in a few seconds, so you can do it while walking.
