User reviews

Expensive and Useless

Not giving its Pro features on iOS and iPadOS. Giving only simple feature with yearly charges which iPad default PDF app already have.

Great App

It’s really helpful program and I like working on it l, give me great support to manage my projects documents

Disappointing

I have Nitro pdf pro 14 on two of my PC’s. It’s great. I accepted the free Nitro pdf Pro trial that gave me the same tools on my ipad with access to all my recent files but I could not justify the cost. This app for a more reasonable price promises the same features but utterly fails to deliver. The support link gives contact options for the various PC and Mac offerings but not for the ios product. You can combine pdf files but it is impossible to reorder them. You can only rotate or delete. The help link takes you to something called Pdf pen. There is no way of contacting support directly. I am going to have to cancel.

Crashes repeatedly on iPhone. Yes, my iOS is up to date.

It crashes when opening PDFs from websites email attachments, and attempting to save markups. It also consistently does not save documents after performing markups or trying to save a PDF. It has difficulty creating new folders to save files in. I have to make the folder using a different app and then try to save it, which also fails repeatedly.

GARBAGE! SAVE YOUR MONEY

This app is useless. The editor app that comes with iphone works better than this. You cant even rotate pages. Save your money.
