Customer Reviews

Very good app!

I like the app very much, especially when I am using it in split view, but I am missing many of the controls I had in iAnnotate, such as going to the previous page I was or previous annotation and so on. Instant copy of a portion of some page to the clipboard and attaching it to another page also is great in iAnnotate.
Also I would like to see the capability of showing a gif animation added as a picture to a page, or linking a short video. It would be great if it also support some latex in the notes.
It would also be great if the hand written notes be more pretty and use pressure sensitivity of Apple pencil.
I am using both pdf Connoisseur and iAnnotate, but at some point I would like to kiss one of them goodbye! So far the main reason for not picking iAnnotate is the lack of split view capability!
Good luck to both groups!

Very impressive

I've used a lot of PDFs apps and this one is my top choice, it doesn't require you to sign up for an account, it can easily access you cloud information from one drive/ google drive and many more.
This app also has a built in text reader. This is extremely useful! It doesn't require the internet like Siri to read the information so there's no data charges and your able to change the speed quickly to read faster or slower.

Screen shot in clipboard

This is a very nice PDF reader. I started to use this, because iAnnotate so far has not adopted the split view. This app also has some advantages compared to iAnnotate. For instance it highlights the links. In notes I can add mathematical symbols with subscript and superscript. It is also missing many advantages of iAnnotates, such as screen shot of a portion of the PDFs and adding it as an image to the other place without saving it in camera roll. I am playing with both of them, and we will see which one is more agile to become more flexible.
