    Stop asking me to rate - I have rated the program before - it is annoying!
  • Dishonest - DO NOT BUY!!

    By Music_Kritick
    Buyer beware!! I purchased this app a while ago, and it was working fine. I actually enjoyed it. But then they put out an update and now they want me to pay another $9.99 to get the features I already paid for. That is dishonest and a scam!!! Do not purchase!! Find another app!
  • Love it’s use, but hate that the app doesn’t sync on other devices

    By Sisteradams
    I love the functionality of this app. The only thing I hate is that it doesn’t sync with my other devices. I have the app on all of my apple products ie iPhone, iPad Pro and MacBook. I wish I could see all of my documents in the app on all of my apple products. But it doesn’t sync. That’s the only thing I hate about this app.

  • It’s a great app but..

    By Loady420
    I have been using this app a few years now. I have installed on my phone and iPad Pro 9.8. Other at my company also have the app. One problem I keep running into is when I try to save to iCloud it says “you can’t save file to a read only folder.” I then have to delete the app and reinstall sometimes that does not fix it and I have to restore the iPad.
  • Better Than Adobe Any Day of the Week

    By 1MidwestMadMan
    I have been using this app for 3 years now and the options only continue to outperform my expectations. This app has transformed the usability of my iPad and iPhone. I use the Readdle app bundle daily and can’t see how I ever managed daily business without them. This app and the associated apps are a must if you require limited resources and are always on the move. Great job and keep up the great work Readdle!
