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.

The ultimate F-Droid setup (300+ Apps)

WHAT IS F-DROID ? F-Droid is an awesome app repository for FOSS (Free & Open Source Software) android apps. From productivity apps to games, f-droid has (almost) everything you need. Hope you will discover useful FOSS apps to free your phone from Big Tech^^ REPOSITORIES : This list includes apps from the official f-droid repo but also from IzzyOnDroid and some customs repositories which will be always linked so you can add them easily. CATEGORIES : F-Droid clients Utilities Social & Communication / 8 subcategories Health / 7 subcategories Customization / 3 subcategories Gaming / 3 subcategories Internet / 6 subcategories Productivity / 15 subcategories Privacy / 5 subcategories Security / 4 subcategories Media apps / 10 subcategories If you care about privacy check : Privacy focused OS for everyone My privacy and user friendly setup For more FOSS Android apps check : Beautiful Open Source Apps for Android DISCLAIMERS : Adding custom repo might not be as secure as the official one so I'm not responsable if you encounter any problems with them ! I encourage you to do your own research about it ! Also while open source is great for privacy and security it is not perfect. So keep that in mind before downloading any apps. Most apps that I've listed are privacy friendly but some might be not be perfectly private and secure. I again encourage you to do your own research about them. I am not a privacy and security expert. I'm also don't consider myself as a developper so I do not have any technical knowledge and so I didn't look into any source code of any apps in this list !

Privacy-friendly apps I've used and liked

This list covers many privacy-friendly apps I really enjoy. My setup is primarily Apple-based, but I've used Linux and Android in the past and tried to add things that work with them as well. For every Apple app listed here, I've also listed alternatives where possible and I expect you to have activated full E2EE on your Apple ID. Apps are listed in a somewhat organized way, usually from most simple/feature rich to most private.
