A free program for Android, by Balto Wolf Studio.
How does it work?
The app will try to determine the file format of the document you're trying to read and then it will load the appropriate reader. If you're reading from a website, you can also choose to have the app load the website reader instead.
It will also allow you to change the font size and line spacing to make reading easier.
You can change the speed of the reader and the app will keep pace with your reading speed. It will also allow you to pause the reading and resume it later.
What can I read?
It supports many document types including TXT, PDF, EPUB, FB2, HTML, DOC, ZIP and Kindle (non-DRM-protected) eBooks.
