Readgio for iPhone Duo

01 / The story

A phone that opens.
A reader that gets it.

Readgio, the EPUB and PDF reader with automatic reading statistics, brings a book-like experience to iPhone Duo. The design follows a simple idea: the outside is the cover, and the inside is where you read.

With “Cover when folded” enabled, the book’s cover fills the outer display. Unfold Duo to return to the text. Close it again, and the cover comes back, just as it would with a physical book.

The fold becomes part
of the reading experience.

A closer look.

03 / Made for the fold

More than a bigger page.

Open it like a book

On the inner display, a two-page layout gives the text room to breathe. Animated page turns, adjustable typography and reading themes make it easy to settle in. A bookmark ribbon sits at the fold, ready to save your place.

Put the book down. Keep reading.

When Duo is partially folded with the lower half resting on a surface, Readgio moves the text above the hinge. Page-turn buttons, reading progress and other controls sit below it, so you can turn the page without reaching over the text.

One more chapter?

Chapter-time estimates help you decide whether there’s time to keep going. Highlight a passage, leave a bookmark and return to the lines you want to remember. Reading time and progress are recorded automatically as you read.

Your books come with you

Readgio opens your own EPUB and PDF files, with offline reading and optional iCloud sync. The expanded library makes room for books and collections, while statistics show your reading activity over time.
