The Best for Healthcare Professionals

I use this application on a daily basis as a pharmacist in a major medical center. I'm able to synchronize PDF Expert with my DropBox where I store thousands of critical documents in various folders. I use this app to index, search, organize and annotate these files. When I need information quickly, I've not found a better program yet. Make no mistake, PDF Expert's ability to search thousands of files by content or file name is nearly as rapid as Spotlight on OS X.

The developers are CONSTANTLY making updates and are incredibly receptive to feedback. This is a MUST HAVE app for the busy healthcare professional seeking to organize and quickly access his/her documents (journal articles, presentations, monographs etc.) while on the job.

This app does nothing?!?

I don't understand. Did I get the wrong app downloaded? This app doesn't open PDFs. It shows you a list of the PDFs that you tried to open in it, but you can't do anything with them except upload to iCloud or download from iCloud or attach to emails or open in other apps. I wanted to open and fill one out and there's no way to do it, when I hit the Open button it just shows me the iCloud file list, and when I pick one it just downloads it, and it's still not open. Or maybe it can… There's a user guide included, but it's a PDF so you can't open it, so I can't read it. Who needs this app, why in the world is this an editors choice, why is everybody leaving these reviews for an app that does nothing?

Deleting this complete waste of my time. Thanks for nothing, Apple editors.

If you're reading this review thinking about paying $9.99for this,DON'T DO IT. It's a complete scam. I think all these positive reviews were bought. This app doesn't do anything.

Amazing!!! Download this app

This is one of the few apps I wish I could give more than 5 stars. I have been searching for a way to edit and attach .pdf files from my iPhone for months.

The app is extremely easy to use, it actually works as a better pdf editor than the full Adobe program on my laptop.

I need to modify and email .pdf files constantly in my line of work and this app makes it easy.

My favorite feature is that the app actually solves one of the major problems with the iPhone and iOS software. I can now attach a .pdf file to an outgoing email from my iPhone as an actual attachment that displays like a normal email attachment when you open it on a desktop computer. Before this app the only solution I could find was either to send the Dropbox link (very unprofessional) or go through a cumbersome process involving some weird editing apps on my phone which still wouldn't work right half the I can attach a .pdf to any email directly from my iPhone with ease. For someone who does business on the go with limited access to a desktop computer this app is a game changer!
