Similar to the #VolunteerComputing / #CrowdContribution discussed previously, I've also been on-and-off contributing to the #MissingMaps portion of the #HumanitarianOpenStreetMapTeam project: https://www.missingmaps.org

I've long dreamed of one day putting together an #iOS / #iPadOS client that lets me use my #ApplePencil to draw building outlines to contribute. Until then, I'll keep contributing through #HOTOSM & #MapSwipe: https://mapswipe.org/
