Read your EPUB and PDF files in one app. The same calm reader on your phone, tablet and computer — free and without ads.
The same app and the same screens on Android, iOS, iPadOS, macOS and Windows, showing one page or two to suit each screen.
One-handed on the commute, with a library of covers
Magazines and textbooks as two-page spreads
Organise your library and read for hours on a big screen
Sign in and the reading position, bookmarks and highlights of your own EPUB and PDF files and your purchased books sync to your other devices. Pick up on the tablet or computer exactly where you stopped on your phone. Your own files send places and colors only, never note text, and sync can be turned off at any time.
Sign-in uses a TOBESTBOOKS account (free to create).
EPUB books such as novels and essays reflow to suit your eyes; designed PDFs such as magazines and textbooks keep their original layout.
Change the font, size, line spacing or margins and the pages reflow. Pictures and photos in the book fit the width of the screen.
Designed pages appear as they are, with two-page spreads on wide screens. On a phone, Fit Text trims the margins so the text reads larger.
Calm like a printed book, with the tools you need to study a book in depth.
Double-tap the middle of the page to drop the margins and fit the text to the screen width. Fit page, fit width, fixed zoom and two-page spreads are there too.
On a tablet in landscape or a computer, EPUB and PDF alike open as two pages side by side, like a book.
Find books by title or author and sort by recently read. Books in the same series are grouped into collections automatically.
Paper, Sepia, Green Paper, Dark, OLED Black, Bedtime and more. Adjust brightness and warmth, and switch between day and night themes automatically.
Font, size, line spacing, letter spacing, paragraph spacing, margins and line length. Add your own font files as well.
Highlight in four colours and add notes. See contents, bookmarks and highlights in one panel; search the full text and export as Markdown.
Hear the text in your device's voice, at the speed you choose, with the screen kept awake while you listen.
Add a folder of books and they appear in your library without being copied. Your original files are never changed or deleted.
There are no ads or analytics. Your own files stay on your device; sync sends only reading positions and highlight places, never their note text.
There are tools for bilingual editions and commentaries too: Korean–English side by side, and Bible references that open in place. Read the guide
Everything but the text steps aside. Tap the middle of the page to show or hide the toolbars.
Choose a theme and set brightness and warmth once; every book opens the same way.
Never lose your way in a long book. Move between the contents and your marks with a tab.
Imported files, linked folders and purchased books come together in one place.
Install, add books, read. The guide has the details.

Yes. The app is free and has no ads. You can read your own EPUB and PDF files without signing up.
EPUB and PDF. Any DRM-free file opens, and ebooks bought at TOBESTBOOKS (tobestbooks.com) are read in this app too.
Books protected by another store's DRM can't be opened. The app tells you when you import one; please read it in that store's app. DRM-free EPUB and PDF files work wherever they came from.
The app has no purchases. Buy at tobestbooks.com, then sign in to the app with the same email and download the book under Purchased.
Up to six devices per account. To add another, remove a device you no longer use under Manage Devices in the app. You can remove devices up to three times in 30 days.
Yes. Purchased books you have downloaded open offline, and a network error alone never locks a book. You only need a connection to download new books and to sync.
When you are signed in, the reading position, bookmarks and highlights sync to your other devices. Your own EPUB and PDF files continue when each device has the same file; only places and highlight colors are sent, never note text, file names or book text (notes stay on the device where you wrote them). Purchased books sync notes too. Sync can be turned off in the settings on the Purchased screen.
No. Imported files are copied into the app, and linked folders are only read. Removing or hiding a book in the library leaves the original file as it is.
There are no ads or analytics, and your files and reading history stay on your device. Only when you sign in do we keep purchase and device records and synced reading records (reading positions, highlight places and the like) on our server. Book files and their text are never sent. See the privacy policy.
Store apps are updated by the store. The Mac and Windows apps downloaded from this site tell you about new versions and update themselves.
Sign in to the app and choose Delete Account, or follow the account deletion instructions. After deletion you can no longer download or read purchased books, and this can't be undone.
Install it on every device you use — phone, tablet and computer. Sign in with the same account and continue reading on any of them.
The Mac and Windows apps downloaded here update themselves when a new version is out. Latest version
