The reading experienceA reader that feels like
A reader that feels like
a personal library.
Designed around familiar book habits: shelves, bookmarks, margins, annotations and quiet focus—without making every screen feel like a settings panel.
Paper-like focus.
The quiet intelligence of a good reader

Useful actions, one selection away.
Context actions can be arranged around the way you study and read.

Interface and book typography stay independent.
Choose from 16 app themes, import a TTF/OTF app font, then separately import a Reader font for document text. Page margins, line height, headings, alignment, hyphenation and indentation are tuned in the reading layer rather than forced onto the whole app.
