SmartQ Reader

More than just a PDF reader

Organize, Annotate, Share for free!

THANK YOU FOR YOUR SUPPORT! Installation of another APK is NO LONGER required! It’s all about historical compatibility issues with devices running Android 2.2. Unfortunately we got quite a few one star comments for this :-(

The awesome SmartQ Reader provides you the fastest PDF viewer ever. With it you can easily access your PDF documents from almost any Android devices. Reading experience has also been greatly optimized for modern phones and tablets. Annotation, page cropping and sharing are not only useful and convenient but also bring you lots of fun. The built-in file manager helps you organize your documents, and sync them safely over the internet.

The ultimate goal for us is to build a powerful PDF Reader, professional, yet user friendly. We are working really hard to make it better and better. Plus, SmartQ Reader is, and will always be, FREE for anyone to use.
