About

Timebound EPUB Reader

Read full description

Timebound is a focused reader for your own DRM-free EPUBs — and a library of thousands of free classics to fill it. Import the books you already have — from Files, iCloud Drive, or AirDrop — and read them in a calm, page-turning view built for long stretches. Or browse the built-in Project Gutenberg catalog and download complete, public-domain classics — Austen, Melville, Shelley, and thousands more — free and yours to keep. • Browse and search thousands of free public-domain books, and download them in a tap • Adjustable typography: typeface, size, margins, line spacing, and justified or left-aligned text • Light, sepia, and dark reading themes, or match the system • Turn pages or scroll continuously • Search the full text of any book • Table of contents and tap-to-resume — always back to your exact place • A tidy library with cover, list, and grid views • See your place as a percent, a book-wide position, or a chapter page No store, no accounts, no DRM — just a nicer place to read the books that are already yours. Books in the catalog are provided by Project Gutenberg (gutenberg.org). Timebound is independent and is not affiliated with or endorsed by Project Gutenberg. Catalog browsing relies on Project Gutenberg's public service and may be unavailable at times or change in a future update; the reader and your own imported books always work regardless.
