Hello,
I'm looking to maximize my efficiency, and am interested in the notability app.
I already have PDFs Expert and the default notes app going.
I hear a lot of praises for notability however, but I'm curious to know what exactly does notability do, that the notes app (taking notes obviously) and PDF Expert (digitally sign and edit PDFs) doesn't?
IMO, notability is less featured than PDF expert, and that's precisely what I love about it. The various annotation options are more readily accessible in Notability, unlike PDF Expert where they are squirrelled away in menus.
As a teacher, I have all 3. Notes is for taking quick notes which I can then share with other people via the myriad of share sheet extensions. PDF expert has the "downside" of syncing annotations back to Dropbox, which I don't want (I want the original versions intact in Dropbox), and has this annoying wrist guard border which appears when I zoom too much into a document. Very distracting when my ipad is mirrored to my classroom projector and the whole class is watching.
PDF expert is great as a file manager however, and I do have my Dropbox files synced to it so I can access my files even when offline. It has the best annotation features, but because there are so many of them, accessing them can be slower and feel more cumbersome.
Notability silos my PDF documents in its own app, leaving me free to annotate on them to my heart's content.
Again, this is just my own scenario and use case, so your mileage may vary.
