Blubb Reader
Read, listen, study offline
Free · Designed for iPad. Not verified for macOS.
Blubb is a free reader for books and research papers. Import EPUB, PDF, text, and scans, then read and listen offline.
For research papers with an available arXiv HTML edition, Blubb offers a formatted view that preserves equations, figures, tables, citations, and working links. Keep the original PDF at hand and change the reader's font, size, theme, and page or scrolling layout.
On-device voices read aloud from your last position. Notes and highlights stay with each book. Alice's Adventures in Wonderland is included to get you started.
No account, subscription, ads, or tracking. Your imported books and notes stay on your device. iCloud sync is under development and unavailable in this release.
