PDF Reader

Very useful app for organising your PDFs into folders as well as a secure folder. I've only used it for a short time, but have found it better than several others that I've tried. It is fairly intuitive so doesn't require a lot of effort to get to grips with things such as storing, moving between folders, making new folders, annotations, sharing by email etc. I would thoroughly recommend.

It's one of my most used apps

Could you adjust the toggle for the text autoflow such that there is more adjustability for faster flows for us speedreaders, whereas right now, on the far right of the slider, within .01mm it goes from a moderately slow speed to way too fast.

Also, a nice to have would be a read out loud functionality, then I could stay completely with this app!


A must for every iPhone.

This app and an app that hooks my phone to a printer makes my phone a personal computer in my pocket.

Simple to use touch controls that don't take long to master, but you have to persevere to begin with.

Only thing I have missed is the ability to directly enter text to a blank pdf, scanning, downloading, no problem.

And identifying which icon does what can be a struggle but their contents are laid out well so once you have that figured out its smooth sailing.

I particularly like bookmarks, quick and easy to use.
Worth anyone's time and money, a nice piece of work.
