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

Great app but problem with having more than a couple of files

I find this app great for my work with pdf files but after storing some files on the app I can not open and it says ‘want to store more file? Sign up to Kdan Cloud to unlock the file restriction’.
Even though registration is free, if you do not want to get yet another cloud service you are trapped and I could not find information on the actual restriction as to find a way to work comfortably within he limits of it (is it number of files?if so, how many?) without this is definitely a 5 stars

Developer Response ,

Hello, the free version enables you to store up to 10 files within the app. If you store files more than 10, I would suggest you to back up files to your personal cloud and remove unnecessary files from the app. The Kdan Cloud offers you an easier way to transfer files across your devices (cross-platform supported). If you still have questions, please feel free to let us know. Thank you. :)
