There's no commerical interest for me. I found a nice and simple DAM that seems to do the trick for me and that I want to share. It manages photos in a directory ( and subdir ), can handoff to external editors (Affinity, Pixelmator etc) and understands keywords (IPTC, Exif, xml). Have a look at Lyn, if you're just like me don't want to start using Lightroom and are missing a DAM tool.
