  • PSA - when in doubt reboot phone

    By Arduous
    A public service announcement - if this or any app begins to act weird after an update, try rebooting your phone (hold power; slide to power off). That should fix any update glitches. Now you know, and knowing is half the battle. Go Joe!

  • Inconsistent wrist protection

    By Othree123456789
    The app has all the essential features and I used to prefer it over all other pdf apps. Unfortunately, however, when annotating PDFs using an apple pencil, the app becomes very sensitive and inconsistent. Quite often it moves the page or simply refuses to write when the hand (with the pencil) is placed on the iPad. This problem is extremely annoying and appears even though the “wrist protection” feature is turned on.
  • Excellent App

    By Tabatabaei
    perfect, but some misspelling happens copying the text!
  • Last version is buggy

    By Motasem I. Matarneh
    There are a few issues with the last version. The files freeze sometime for no good reason while annotated. When you zoom you no longer can edit or markup the files. Test markup suddenly change location when you zoom in. Good app but please fix these bugs, so i can give you all the 5 star you deserve.
  • Great

  • I do not understand the hype

    By ga7045
    You cannot edit PDFs without significant issues. Certain letters won’t work: the “k” is a “b” so I cannot type certain letters. Not good. Formatting doesn’t match so what you are able to edit sticks out like a sore thumb. There is no way to copy formatting, huge issue. And their help is far from effective. They want you to send them files. And there is no follow up. Good luck finding help on your own via their site. And this is not an isolated incident. It has been very pdf I have tried to edit. I had to use Adobe to get it fixed. I have no idea how they can justify having people pay for this.
