  • App shuts down periodically

    By Dgtor
    I have been using this app for almost 3 years taking notes on pdf. Recently, it’s been freezing and shutting down at least couple times a day and I ended up losing several annotated files as a result. I learned my lesson and purchased notability today. If you are looking for a app to read and edit pdf, get any app other than this one unless you are looking to throw away $10.
  • Works well, but would be nice if annotation could be one tap

    By dc2001
    Currently takes two taps or a finger slide then tap - not great if taking nots in real-time
  • Costly

    By Yzd8
    Why I should pay for the app and then pay $10 more to edit on a PDF file!
  • Please fix edge detection

    By msaif41
    App fails to detect Apple pencil or finger at the edges of screen/paper PDF. I do not have this issue with Apple Notes, for example. This is my one major peeve. Otherwise, fabulous app.
  • The best PDF viewer for me

    Big thank to developers for creating the app! No adds, fast performance. Keep it up!
  • Can’t rotate a pdf? Seriously?

    By bitkahuna
    This app just feels very simplistic.
  • Misleading

    By RM2988
    It’s a good app. It does what it says. My review is based on how the developer markets this app. After you buy it for $10 which is steep for a PDF app when there are so many free versions, you then learn it’s not the full version. Of course you already paid $10 and it’s nearly impossible to get refunds for app purchases. So it will cost you ANOTHER $10. This means the app actually cost $20. It’s misleading and unnecessary.
  • Limited capture ability

    By afvg123#$&tyi
    I cannot download a complete, long article into the app. I will not update with this limitation.
  • Stagnant sometimes

    By Phuongbot
    Sometimes the app stops working and erases all of my work. Please fix that bug!!!
  • Apple Pencil?

    By InSearchOf
    I just assumed this would support Apple Pencil. I logged in and even paid additional funds for other functionality. Pencil did not work and then it did - after a delay. I had already moved on to another app. Perhaps the learning curve someone referred to.
