2ndBook is a free e-book library and reader. Keep all your books and files in one place, read EPUB, PDF, MOBI and DJVU formats, sync your reading progress across devices, and save the quotes and passages that matter with highlights and bookmarks.
What to test in this beta:
• Browse and search the book catalog
• Add a book to your library and open it in the reader
• Read across formats (EPUB, PDF, MOBI, DJVU) and resume where you left off
• Sync your progress, bookmarks and quotes across sessions
• Download books for offline reading
The app is completely free — no ads, no in-app purchases, and non-custodial (we never hold your money). Please report any crashes, layout issues, or files that fail to open. Your feedback helps us make reading smoother for everyone.
