very nice, but lacking obvious functionality

Great app. It has one of the best marking tools, but I miss better navigation buttons such as page up/down buttons and shortcuts as well as "hand" to scroll.

Preferred tool for taking note and reviewing papers

Let me say I have tried every pdf tool around, no exception. I bought many of them to see the full features. This one is my currently preferred tool for reviewing papers.

It’s far from perfect, though, and it has some annoying points missing, specially two:

(i) it’s not possible to edit a note on the right section of the screen, or jump to the note in the pdf when selecting it. Finding the note on the page is cumbersome.

(ii) it’s not possible to use a pen to make annotations, writing by hand, or arrows.

Also, it’s not possible to adjust the border between the pdf and the notes when side by side.

The search feature is a bit too basic. Also, the zoom on the iPad works fine but on a mac needs to improve.

Having said that, this tool is a must. I have combined its use along with pdfexpert and marginnote.

Massively overpriced, missing basic features

This has app has two tricks, but lacks many basic features.

Just short of $50 a year for a PDF app that has poor search, no outline or contents navigation.

The markdown export is nice, but sorry the search is terrible. There is not way to see your search results without clicking through them one by one… that makes the app unusable for serious academic work.

For half the price it would a great app, but at this price it's a hard pass. It’s

I suspect there would be a lot more sales of an app like this if the price weren’t so steep. Students especially will struggle to pay this price.

For the full price you would expect it to be feature complete, especially when competing apps are held up against it.
