  • Librum: Open-Source e-book platform
    I've been rather happy with Librera, although when reading foreign languages, I prefer KOReader for its locally installed dictionary lookups (you have to add them). Note that these are both reader software, first, and not advanced... - Source: Hacker News / almost 3 years ago
  • Accessibility barriers with Kindle leave me wanting DRM-free books to read. Can anyone recommend authors who have their work available through something that isn't Kindle? I'm more than willing to pay for books.
    On Android, the text-to-speech I find is better with https://librera.mobi/. Source: over 3 years ago
  • Maths textbooks/resources suitable for viewing on mobile devices
    I use Libera which has everything I need for a reader, to view full-screen is essential bc it makes use of all the space on phone. Source: over 3 years ago
