## What is Focus Reader?

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: serif and sans-serif fonts for Latin and Korean, with size, line height, and UI scale controls.
- Reading themes: paper, sepia, green, solar, night, and dim.
- Dictionary lookup: long-press a word for an offline definition in the bundled English-Korean and Korean dictionaries.
- 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. The Korean App Store price is ₩4,000; prices in other regions are set by Apple.

Supported formats: PDF, EPUB
