It's a great replacement for the default reader pre-installed on my Pocketbook Touch Lux 4, many customization options, support for a wide range of formats (pdf reflow), custom dictionaries, fonts and more. There are some platform specific issues related to screen suspension on my device and it seems that none of the devs own a Pocktbook themselves, so it may take a while before these get resolved. I can't say how well it holds up on other e-Ink devices by comparison, but overall it is still a step up from what you get out of the box and it gets updated on a monthly basis.
Well, seems like most of the issues I had have been fixed by the latest update. [Edited by sowij, September 21]
it's perfect. reading experience is literally perfect.
on Android it's slow to visually browse huge libraries and can only open files from it's own built-in browser.
It's also an awesome app for Android tablets. You can change the screen's brightness, and make the reading process much closer to an actual E-ink reader.
The best app for reading. It is optimized for e-ink but works great on any device. I really like how lightweight it is. Takes a while to get used to the controls, but it's worth in the end.
One of the most functional e-reader app that's open source. Lots of options and runs quick even on old devices.
Great for eink devices but if you use a normal android device use Librera, its much better.
