Is there a free android app that can be used to edit osm on -the-go? OsmAnd is a freemium. It can be tremendously helpful for areas wirh outdated aerial imagery…
Vespucci is a full-scale editor for Android. There are also more restricted apps such as Everydoor for POI mapping and StreetComplete to fill in additional meta data for objects that are already mapped.
I use Organic Maps for most of my navigation. It also has a pretty decent lightweight editor for adding and editing POIs. You can also leave comments in OSM for coming back later, I strongly recommend it. Here is the link: https://organicmaps.app/
For any serious editing on Android, I use OsmAnd~: OsmAnd~ | F-Droid - Free and Open Source Android App Repository
