Description by 俊杰 沈 Written by the developer, not by AppBrain. Click to read.
DuoFolio is an immersive reader built for iPhone Duo: one book per screen, true two-page spreads.
A layout engine designed for the fold — unfold for a bound book, fold for a single flowing column.
· Two-page spread: reads like a real book, separate left/right pages with a paper-feel gutter
· Cover bookmark: close the phone and the outer display shows cover, title & progress — flip open to continue
· Local-only: your EPUBs stay yours. No account, no upload, no tracking
· Refined typography: serif faces, tuned line spacing, paper-tone themes for long sessions
· Position memory: column-accurate progress that follows you across folded, half-open and fully open
Import your own EPUB and start reading.
