# [OS X TeX] Best iPad PDF viewer for math?

Fri Aug 21 19:41:02 CEST 2020

Skim does not make a PDF viewer for iPads. What iPad PDF viewer most closely matches the capability of Skim, especially in regard to math documents? I can view my PDF documents in the Books and Safari apps, but they don’t seem to give me the table of contents in a readily accessible sidebar, don’t have Back and Forward buttons (pages in order of viewing), can't navigate by logical rather than physical page, and don’t give a thumbnail of a \ref if I hoover the cursor over the \ref.

There are a bunch of these viewers available, and I’m hoping that someone has already done research so I don’t have to.

It would be wonderful to be able to be able to carry around 200 page math documents in a svelte one pound package like my iPad Air.
