Spent hours looking for some simple pdf viewer to read and comment on pdfs, all of them where trash: except this one. No requirement to register even to open the app was a good start and the software is fairly functional from the point of view of what one would expect from a reader app plus it has editing functionality as a paid version for those who are interested. It does not require a pdf library creation (why does every other software need to create its own pdf catalog rather than just open files from storage?) It basically picks up where the standard Apple preview app leaves the chat, it adds bookmarks, comments, and remembers the last location in a pdf. The only thing, while the app supports multiwindow mode, the software does not make it apparent by missing sort of “open pdf in a new window” menu options of a document, but you can work around that using standard iPad window management.

I am unable to open large files in this app

This is a very good app, even for the free version. I will give 5 stars if there is a pop-up preview for the link. It tiresome to read a PDF paper[1] with this [2] kind of references.

Really easy to use and well designed visually and from ease of use

软件使用起来非常方便，能可以读写并储存文件到ipad本地，功能齐全不阉割

用的好好的 忽然出现这些情况 为什么啊

iPad文件里的pdf打不开终于找到一个布局一样的软件特别好！希望可以增加一个左右滑动切换pdf的功能，这样不用点掉上面的标题栏出去选了。

订阅之后为啥仍然无法使用pro功能啊

Feedback in the end of September, after 2 updates, still no fix

很多pdf阅读器都有两种橡皮擦，像素橡皮擦和对象橡皮擦。你们是否可以增加对象橡皮擦呢。
