Overall great app at a resonable price. Only problem is that the natural ink option does some weird things to drawing. Otherwise really good work

I love it!

after the new update my pdf no longer works. it cannot open the file

I tried using it for making notes and writing down dimensions on plan drawings with my apple pen. All works nicely, good interface and liked auto syncing with dropbox. But it has been so many time when work was lost and unsaved that I just cannot recommend it for professional workflow,

Probably the best (not perfect) workflow for annotating PDFs I have tried. I usually use the ios Files app for annotating PDFs because it has the shortest and efficient workflow for using the pencil (writing and deleting), changing colors for highlighted text and adding comments, but it is not always stable. Other PDF annotation apps you have to click way too many times for simple annotation i.e. hand-written notes with the pencil, and adding and editing comments/highlights. In this app I would love to see that my comments would also work in the Preview app in macos. They only show in Adobe reader, which is a big downside. Also, when I highlight text it would be nice I could select highlight color immediately and not having to tap and extra time to get another menu.

Very unstable, crashes, sometimes can’t browse any files, and the auto save isn’t reliable for markups. I even bought the premium version.

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
