KOReader is not “fake epaper”, it’s an app designed to be used on ereaders which means it’s UI is high contrast. FWIW I agree it’s not ideal for an OLED phone screen, but it’s definitely not fake epaper (more like the opposite) and makes me think you might be accidentally using something else?
(Also KOReader is not for “certain” devices, it’s FOSS and installs on basically any ereader, including Kindle, Kobo and anything running android like Boox).
What CWA does is it integrates a KOreader sync server (can also be ran independently). In future updates CWA’s web reader will sync with this progress, but for now it only shows up in the UI like this:

THAT ALL SAID, if you are only using the WebUI and don’t want to wait for CWA to update their web reader, Komga is a simple app (originally designed for Manga but will work fine with books) that has a web reader that will also remember your progress (and fwiw there is a KOReader plugin in case you want to sync that progress with an epaper device in the future).






Booklore was discovered to be vibe-coded and riddled with security issues. The dev shut down the project when discovered. Best avoided for now.
