Also worth comparing
These listings name Preview as their own alternative, so the relationship runs both ways.
Lyn

Preview is already installed on every Mac and free, handling images and PDFs with annotation and signing, but it lacks Lyn's curves, levels and geotagging.

Preview is built into macOS and handles merging and page arranging alongside annotating and signing, but is closed source.
