Readgio

Readgio is an EPUB and PDF reader for iPhone and iPad designed for readers who want a calm, book-like reading experience and an easy way to follow their progress. Import your own books and read offline, whether you’re opening an EPUB or a PDF.

Readgio automatically tracks reading progress, speed, sessions, time spent, and daily streaks. You can save and highlight quotes, get gentle reminders about saved passages, and sync your library across devices with iCloud—or keep books only on your phone.
