Document Viewer is an app that lets you view word documents in different formats: PDF, DjVu, XPS, CBZ, and FB2. As long as the document is in one of those formats, you can comfortably read it using your Android.
Much like other similar apps, Document Viewer lets you customize the interface to adjust it to your needs and preferences. You can adjust the brightness, hide the notification bar, use taps (instead of swipes) to change the page, and much more.
Document Viewer is a powerful text document reader for Android that offers good format compatibility, a simple interface, and a bunch of customization options. But just in case that wasn't enough, it's light and doesn't take much space in your smartphone's memory.
