EinkReader is a calm, fast reader for EPUB and FB2 books on your phone, tablet or e-ink screen.

THE LOOK OF E-INK ON ANY SCREEN
Black text on a glowing white page can be harsh. EinkReader lets you soften the black level with a single swipe, so the page looks like paper or an e-ink display. The setting is remembered separately for day and night, so the night theme can stay deep black while the day page stays soft.

EASY ON THE EYES
Swipe up or down on the left third of the screen to change brightness (down to 1%), on the middle third to change contrast, and on the right third to add warm light for the evening. No menus, you never leave the page.

BUILT FOR READING
• EPUB, FB2 and FB2.ZIP files from your device, added with the system file picker or "Open with"
• Automatic hyphenation and justified text
• Fonts, text size, line and paragraph spacing, margins, glyph thickening
• Day, night and sepia themes

OPTIONAL SYNC
Sign in with Google to keep your books and reading position in sync between your own devices. Data is stored in a private, hidden app folder of your Google Drive; the app cannot see your other Drive files and the developer never receives your data. Sync is optional: without signing in everything works offline on one device.

PRIVATE AND FREE
No ads, no analytics, no tracking. EinkReader is free. If you like it, you can leave an optional donation inside the app; nothing is locked behind it.

Note: books protected against copying (DRM) cannot be opened. EinkReader does not include or sell books.
