FBReader vs Koreader in our news:
2024. FBReader for Android improves ePub support
The new version of the popular reading app FBReader for Android 4.0 brings a significant change to the reader core. The developers have replaced the obsolete zip archive support with the modern libzip library. That means some ePub (and other zip files) that were not openable by FBReader will work now. On the other hand, any change in the core is potentially dangerous. Please report if you found some crashes or slowdowns with this release. Other new features include new appearance option: “Neglect screen notches”. It is helpful for devices with a wrongly detected notch, e.g., if the front camera is hidden under the screen. The app stores the correct reading per cent now. Reading progress will be shown correctly in the library. However, you have to open a book with the wrong indicator to fix it. The footer is visible over the reading-aloud panel. You can optionally switch to the old behaviour.
2022. FBReader starts a new cycle of Android updates
FBReader has recently launched its first Android update since April 2021, introducing version 3.1 and commencing a new cycle of Android enhancements. This release incorporates several notable features. FBReader now has permission to access the filesystem on devices running Android 11 and higher. Additionally, the Premium Edition has restored access to all TTS (Text-to-Speech) engines. The update also implements support for new bookmark styles introduced via the desktop version, although it is not possible to add or remove styles on a mobile device. Furthermore, buttons are now visible in all dialogues, and the broken Yandex Translator has been replaced with DeepL. Finally, the issue of incompatible cache has been resolved, eliminating the need to reopen the current book.
2022. FBReader for Mac is out
Popular ebook reader FBReader 2.0 for Mac can now be found on the Mac App Store, expanding its availability to three major desktop operating systems: Mac OS, Windows, and Linux. The reading mode and library view, including cloud sync, are mostly complete. FBReader supports a wide range of book formats, such as ePub, fb2, fb2.zip, mobi, rtf, MS doc, plain text, and cbz. The rendering engine is equipped with CSS styles, hyperlinks, hyphenation, page headers and footers, text selection, page turning, and text scrolling in two-column mode. Additional features include a table of contents, bookmarks, language selection, advanced text navigation, and a dark theme. Furthermore, FBReader offers a multi-book (multi-window) mode.
2022. FBReader comes back to Windows
After an eight-year hiatus, FBReader makes its return to Windows. The latest release, FBReader 2.0, incorporates most of the features found in the iOS and Android versions, with a specific focus on desktops and laptops. The app is compatible with Windows 10 (build 17763 and higher) as well as Windows 11. Currently, FBReader is exclusively available for the Intel 64-bit architecture, but it can also function on Windows 11 Arm64 through emulation. Unfortunately, the app does not support Windows 10 Arm. FBReader 2.0 introduces a revamped interface, offering both light and dark themes. Additionally, it includes Ukrainian interface localization. The new render-engine utilizes CSS-defined colors, which can be disabled through the preferences settings. Users can find bookmark style options within the preferences dialogue. Furthermore, there is a new feature that allows the toolbar to be hidden in fullscreen mode. In the dark mode, the app automatically decreases the brightness of images. The developers have also added an "Import multiple files" menu item in the library window.
2017. FBReader adds iOS app
FBReader, a highly popular ebook reader available for Android and desktop, has recently launched its app for iPhone and iPad. The iOS version of the app utilizes the same engine as the FBReader app on other platforms and offers support for the same range of text formats. The primary supported formats include ePub, fb2 (including fb2.zip), and mobi (also known as Kindle azw3). Additionally, the reader is capable of opening HTML, RTF, MS Word documents (*.doc), and plain text files. However, it currently does not support "non-text formats" such as PDF, DjVu, and comics. The free version of FBReader for iOS does come with certain limitations, such as a maximum library size of ten books and disabled online translators. To access the full range of features, users have the option to upgrade to the paid version for a fee.
