Good on the features, but lacking some software needs

The individual annotation options are awesome, the color variety is pretty good, and they all seem to work as they were designed to. The app crashes quite a bit, especially if you try to use the search feature, and if you haven't saved in a while, it can be a pretty big loss for your annotations. An auto-save would be really nice, especially since there is a tendency to crash. Also, the news screen and feed are the first things you see, when that's not what anyone is using the app for... it would be nice to have your documents be the primary screen and then if you're interested in kdan's articles, they'd still be available.

Developer Response ,

Hello, thanks for the suggestions, and we'll inform the PDF team of your message. As for the news page, please tap the "Custom" button (beside the "?" button)on the the top right of the screen while you are in the explore page. You can change the layout and set your file list as the primary screen. If you still have questions, please feel free to contact us. Thank you. :)


Finally an app that edits a PDF

I have done most of my editing right on my smart phone which is amazing. There are features to highlight, change font color etc and it's all very simple. I'm not a techie so I've done basic editing tasks however converting a PDF on your phone is an accomplishment. Good app

New version missing futures that I used to work with it!

New version do not do “Horizontal” mode, also the variety of pen colors when away! Can not select the view of my files either by name, date or size only change positions but not view with it.

Hello again,
I think I didn’t explain well my request. I would like to have back the future were I can view my forms in “Landscape mode” I used to have this future and it was very helpful since my clients signed my forms, when I had the landscape mode people have more room to sign on them. Now I can’t do it and the space for people to sign it is very limited. Please let me now if this is something you are thinking to have it back. Thanks.
