BUILT FOR IPHONE DUO Open iPhone Duo and your book becomes a two-page spread, with real page curls. Close it and the book closes: the cover screen shows its cover, leather-bound with the title in gold or the original art. Tap to keep reading, one page at a time. Your place holds through every fold, and turning the open phone to portrait gives you a single page. YOUR EPUB AND PDF FILES Any folder of EPUB or PDF files becomes a library with covers, sorting and search.

Verdict

The call

The clearest difference is rating: Unpaged at 5.0 against CalibReader's 4.3. Unpaged also leads on iOS requirement (18.0 vs 26.2). CalibReader's advantage is update cadence (every 3 days vs weekly) and ratings volume (6 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
