Last I checked, not with StreetComplete. But the OSM wiki has a table of Android apps https://wiki.openstreetmap.org/wiki/Android which column "Record tracks" can be sorted by, to see which apps have that feature.

How I've done similar before is to record a GPS trace with an OsmAnd plugin, upload it to OSM servers, import it as an overlay in the web-based editor on desktop, and used that and satellite imagery as reference to draw in the missing trail.

In a pinch you can also record a trace and edit directly on it in the field with the Android app Vespucci, but its UX is clunky and much less friendly to new contributors than the web-based iD editor.

If you are in the U.S. please each out to OSMUS, they are amazing and can connect you with trail mapping resources. There is a vibrant community of folks keeping our trails mapped!

As the other commenter mentioned the web editor is probably the most beginner-friendly editor. It might seem a little daunting but it's actually not that difficult to edit OSM. When you save your change there's an option to request a review of it. That'll get an experienced contributor to take a look at it and help clear up any mistakes.

OSM also has a public database of GPS tracks that contributors use to aid in mapping. Even just walking the trails with GPS tracking on and then uploading the tracks to OSM without doing anything else is a valuable contribution that will allow other contributors to map the trails at some point in the future.

You can edit existing trails, but directly adding new ones is not intended. What you can do is create a GPS track, and then upload it with a note describing the problem.

I use the app Vesspucci for actual editing, it works well (but larger changes to OSM is a "full PC" kind of task). Notes from StreetComplete (from all users) show up on a TODO list in the app, so the more advanced users can decided on whether they want to create a node on the map from the note.

You can record tracks or add places right in the app.

Yes! Accessability quests I often see are: - Do these steps have a ramp? (with several ramp-type options) - How many steps are here? - Do these steps have a handrail? - Is there tactile paving at the top and bottom of these steps? - Does this crossing have tactile paving? - Are there sound signals for the blind here? - Do these traffic lights have a button to request a walk signal? - What's the height of the curb at this crossing? - Is this place wheelchair accessible?

If you want to do more advanced accessibility mapping, also have a look at https://mapcomplete.org/onwheels - same concept, but different implementation. Also OpenStreetMap based, so data you add there is shared amongst CoMaps, StreetComplete, ...

Disclaimer: I make this

Yes! If you want to you could even select to show only accessibility related "quests".

yes, there are questions like that (steps, ramp, etc). Also questions about road surfaces, pavement/sidewalk, etc

A massive effort has been underway for a while to get an iOS build of the app: https://github.com/streetcomplete/StreetComplete/issues/5421

Open source software often moves comparatively slowly, of course, but I believe they're making decent progress.

No, but: https://github.com/streetcomplete/StreetComplete/issues/5421

You can use a different, webbased one: https://mapcomplete.org

any OS INT we contribute can be by definition used by intel agencies. such is the way of the world.

That sounds like an actually socially useful use of their budgets.

But intellegency agencies would like an edge, not that everyone has the same info as them...

Do be useful, can you help us understand why you think this?
