PDF Expert has been an indispensable app for my iPad for almost as long as I can remember (I’m fairly certain it was one of the first apps I bought when I got my iPad). It’s a fantastic app on iOS because it enables me to not only read, annotate, and add comments to PDFs, but it also gives me a cloud-based ‘Finder’ of sorts – enabling me to browse my Dropbox and OneDrive files and sync them to my iPad.
Given my longstanding appreciation for Readdle’s PDF Expert on iOS, I was pretty keen to try out the Mac version of PDF Expert, which launched late last week. But it must be said, I was sceptical of the value it would bring to the table, because unlike iOS, OS X has the Finder, and cloud services like Dropbox and OneDrive already sync files locally. But most significantly, Preview on the Mac is a fantastic Swiss Army knife for viewing documents and already does a pretty great job at viewing PDF documents, annotating them, adding comments, and even performing some basic page re-organization functions.
But despite my scepticism I was pleased to discover that for those of you who deal with PDFs regularly (myself included), you’ll find value in what Readdle has developed in PDF Expert. Rather than a traditional, wide-ranging, review, I’ve decided to focus on three key features which make PDF Expert worth the money – features that ultimately convinced me to turn my free trial into a purchase.
