- The page describes append-only saving and a check after each save; the app is marked coming soon.
Field notes
The page presents a save workflow that appends edits, reopens the PDF, checks it, and offers a receipt; those are product claims, not verified behavior in a released app. Its comparison section describes a test document containing a form field, sticky note, attachment, layer, and page labels, while the feature list also includes certificate signatures and on-device document tools.
