About this app

Lose your place in long documents? Focus Reader reflows PDF and EPUB books to fit your screen and keeps only the part you're reading in sharp focus.

Open the books you already have and adjust text size, font, line spacing, and column width to suit your eyes. No more fighting cramped PDF columns or tiny print.

Features
- PDF & EPUB reflow: the current page or chapter is re-typeset into one comfortable column.
- Focus band: a clear reading band with the rest of the page dimmed, so your eyes stay on the line. Adjust the band's height, dim level, and position.
- Typography: a wide range of serif and sans-serif fonts (Latin and Korean), with size, line height, and UI scale controls.
- Reading themes: paper, sepia, green, solar, night, and dim — easy on the eyes.
- Dictionary lookup: long-press a word for an offline definition (English to Korean, and Korean to Korean). Works offline.
- Library: saved books with reading progress.
- Korean and English interface.

Free and Pro
The core reading features and dictionary lookup are free. Focus band fine-tuning, all reading themes, and column width are unlocked with Focus Reader Pro — a one-time purchase, not a subscription.

Supported formats: PDF, EPUB
