For some odd reason, this PDF reader crashes a lot after the recent Kindle Fire update. Specifically, the app crashes whenever you're reading a PDF document, turn off the Kindle Fire (not shut down) and return later. After a short while, the app will crash and bring you back to the main document selection screen. This has never happened prior to the Kindle Fire update. The good news about this crash (if you can call it that) is that while you are taken back to the initial document selection menu page, you can pick up right where you left off by simply re-selecting the document you was reading prior to the crash and you'll be right back in business. Hopefully a future update will address this issue.

After using ezPDF Reader with the newest Kindle Fire update (6.2.2), I can say that the problem with the recent crashes I was experiencing above is no longer present.


I have the Kindle Fire and the built-in PDF reader in just plain horrible. I'm not even going to go into the details but just trust me, it's not ideal for reading long PDF books and documents. Being that I bought the Kindle Fire mainly to read PDF documents and technical ebooks, I was highly disappointed. When I found out that you can easily sideload apps to the device, I was giddy with joy because I was sure there would be at least one free PDF app out there that would satisfy my needs.

Well I'll give a fair review with Pros and applicable drawbacks or Cons for this app.

(1) This one is probably the best PDF reader app for mobile device out there due to many customization features. However, the developer does not bother the update this app here in If you've noticed that this app version currently, as of date of writing this review, is Whereas, if you go to Google Play you would see that the developer has been keeping the app updated regularly, and currently, to version by 3/16/12. Yet, the price is the same.

(2) Some of the best customization features, or Pros, that are selling point for this app are: (a) importing your own pdf file and (b) have text reflow to fit nicely for reading the pdf documents on your mobile the device, (c) smooth scrolling and rotate pages seamlessly and (d) save the pages where you last read; (e) it also has night/mode just like a book reader app; and, other commonly expect features of a pdf readers etc.

However, here are some applicable drawbacks, or Cons, to the above features: basically these features are short of user's experience:
a) You gonna have to learn manual ways of importing pdf file to your device. This app here on does NOT support Google Doc that the one on Google Play would and that allow you to install "ezPDF Reader Cloud Plugin" (this one on Google Play). Developer's response?? Blaming the Amazon's "policy"!

b, c & d) The text Reflow feature is a nice feature and you will like it. However, when you close the app, while the page would be saved where you left, you will have to Reflow the text again.

I've been using Aldiko Book Reader for reading pdfs on the Motorola Xoom, so this review will focus mainly on comparing ezPDF to Aldiko's pdf reading experience with special emphasis around the Xoom.

ezPDF Reader is an vast improvement over Aldiko for reading PDFs in several of ways:
1) Much more stable on the Xoom
2) Better use of the extra screen real-estate on a Xoom (such as a windowed view of the table of contents rather than a full screen version--less disorienting)
3) "Fitting to Text Column" (aka fit width) feature: awesome feature for making the most of the Xoom's 16:10 screen ratio. Aldiko may have a similar feature, but I never used it if it did.

Other additional non-Xoom-specific improvements/features are:
1) Text-To-Speech
2) Smoother pinch to zoom (Aldiko lags when zooming)
3) Thumbnail support (both apps support table of contents)
4) Quicker access to table of contents (very nice for reference material)
5) Annotation and freehand draw support

Aldiko does have features that beats out ezPDF or that ezPDF just doesn't do such as:
1) ePub format support
2) A fully-integrated ebook store
3) Shelf library view support (both apps support a list view)
4) Better/more-intuitive cataloging feature (ezPDF uses a less intuitive folder technique)

To summarize, ezPDF provides for a better pdf reading experience while Aldiko is stronger at library management and provides a more complete ebook solution. For those that need Aldiko's non-pdf features, I'd recommend complementing Aldiko with ezPDF if you read a lot of pdfs, especially on the Xoom.

In the short (very short) documentation, the highlights are yellow, but I can't find out how to change the color. Anyone else have this problem? If so, WHAT DID... Read More
