U principu odlična aplikcija! Ali u zadnje 2-3 godine sa svakim novim update-om i dodavanjem mogućnosti sve je gora i nestabilnija! Nema šanse otvoriti dva različita pdf- a da se ne sruši! Poruka developerima (mora da će ih biti briga) - više nije i bolje!!!

It would be a nice option to manage the time your copy is saved because you end up with multiple copies when switching apps during work.

Great for annotating and reading PDFs. A lot of additional features in free version of the app as well.

This is by far the best PDF viewer I have used.

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。
