  • Great but suggestion

    By Podcast_Addicted
    Anyway there could be more than 4 color options in annotate mode. Great app though.

  • Excelente app

    Good job is a excelente app
  • Wants more money after purchase

    By wayne.grw
    Wants another $10 after purchasing the app for $10. Prompted immediately after opening. Missing advertised key features until giving them the extra money.
  • Powerful but buggy

    By Domainman
    A trend across Readdle’s products is that anything involving an internet connection is problematic. This eventually lead to me switching away from Spark as an email client, despite loving its UI. The same holds true for PDF Expert. If you only want to work on local files on your phone, you’ll probably love this feature rich app. If you’re planning on using it with Dropbox or any other cloud service, prepare for death by 1000 paper cuts. Weird syncing behavior, overwriting files with old versions, re-creating files you already deleted — it’s got it all.
  • Best PDF Reader

    Thank you for greate and quick update app
  • Images cannot be seen.

    By rnqs
    Previously this app worked beautifully but in the previous version and in the current version I am experiencing a problem in viewing images in pdfs. And I know it’s the app and not the file because opening the file using another app let’s me see the image. I hope this is fixed soon.
