Read, annotate, highlight and mark up PDFs. Designed for scientific papers.
Skim is a PDF reader and note-taker for OS X. It is designed to help you read and annotate scientific papers in PDF, but is also great for viewing any PDF file.
- lots of options to annotate
- like that you can choose more than 5 colors (vs. preview)
Cons
- for those multi colored highlighter users this can get quite annoying, you cannot just select a color and then highlight. and then choose another color to highlight other areas. Instead you set a default highlight color and every time you want a section of document to be in another color you have to select that individual section and change the color (quite annoying for me as I use ~4 different colors, all mixed interchangeably in the same document, when highlighting to mean different things) - there's no way to mass edit your previous annotations (can't select multiple lines/highlights and change their color or move them to a different location in the document) you have to select each individual line and move/change it one by one (REALLY annoying for the "diagrams" I make to add in the side of the documents I edit)
Summary
useful for some people I'm sure, the options seem limitless, but the more you use it the more you realize how annoying little things are that should be simple. Like the fact that you can't select multiple annotations or that you have to click the object and then click the color you want for EVERY line. Tried to write a recommendation about fixing these features and got a seemingly rude response about my suggestion. Overall, I'm not very happy, so I'm on the search for something better.
One gem of a software

Pros
1 Skim has by far the best annotation tools&management in the PDF reader/editor spectrum, and this is including the really pricey apps (My work involves a lot of pdf-reading, note-taking, annotation and form-filling, used to do it mostly on PDFPen Pro and still own the latter, but Skim has pretty much become my default reader/editor, unless I need abstruse PDF-creation functions.
It is the ONLY mac app that allows dealing with annotations in bulk. Annotation/form filling capabilities have never given me any problem, and I filled a good deal of state/tax etc forms.
2 it is LIGHTNING fast, a lot faster than any of the contenders.
3 I don't know about earlier versions, but the versions I've used on Mac since mid-2013 have all been quite stable and reliable, more so than commercial alternatives
4 The interface though not stunning, it stays out of the way , various sidebars on either side of the screen can be used for practical reasons, or turned off with a click for full-screen reading
Cons
Doesn't have detailed PDF creation/bulk-editing tools, not a replacement, say, for pricey publishing-oriented software, but if your PDF-use revolves around reading and typical annotations, that won't be restrictive. All 'core' functions, like printing customization, or dictionary-integration, are there and work like a charm.
Summary
I've been using Skim since late 2013 , and in that period it was regularly updated and I never encountered any error, or problem with forms/annotations etc.
I'm ever surprised by that Skim hasn't gone immensely popular already, as I can't think of a second software that I could recommend this easily (excepting, maybe, Pythonista on iOS)

Good for annotating etc.

Does NOT save text you have written in forms. No warning is given.
Summary
I used to like it for annotating, but it destroyed today's work for me because it didn't save text in forms. There was no warning, nothing. Uninstalling, and will not recommend Skim.
