What it is
Librera Reader is an ebook and document reader for Android, with a browser-based reader also available. It opens formats including PDF, EPUB, EPUB3, MOBI, DjVu, FB2, FB2.ZIP, TXT, RTF, AZW, AZW3, HTML, CBZ, CBR, DOC, DOCX, ODT, XPS, TIFF, PDB, and MHT. Readers can locate files through folder scanning, an in-app file explorer, or a recent-items list. Reading tools include bookmarks, annotations, text search, EPUB3 tables of contents, and configurable Day and Night modes. Reading progress and bookmarks can sync across Android devices through Google Drive. The app also offers customizable text-to-speech with a built-in media player, online and offline dictionaries, online catalogs, and cloud sources. A password or the device’s fingerprint authentication can restrict access. Librera has a free, ad-supported plan and a $5.99, paid once ad-free PRO option. The maker describes the macOS version as a beta; its updates page also links to an online browser reader. The free app’s privacy policy says it may use Google Play Services, AdMob, and Firebase Analytics, and may collect log data when errors occur.
