8 Best EPUB Readers for Android in 2026 (Free & Paid)

Reading on Android means dealing with small screens, touch interfaces, and battery life. Desktop EPUB readers assume you have a mouse and keyboard. Mobile readers need different features: gesture controls, night mode, and offline reading.

ReadEra opens EPUB files with no ads or account required. Moon+ Reader provides extensive customization with themes and gestures. Google Play Books syncs across devices but locks you into Google's ecosystem.

Android-Specific Tips

Gesture controls: Most readers support gesture controls:

• Tap left/right edge: Previous/next page
• Tap center: Show/hide controls
• Swipe up/down: Scroll (scroll mode)
• Pinch: Zoom (PDF files)
• Long press: Select text

Night mode: Enable night mode for reading in dark environments. Most readers support:

• Dark background with light text
• Sepia or warm-color themes

Battery optimization: Keep battery optimization enabled by default. If one reader repeatedly fails to sync, check that app's battery setting. Menu names vary by Android version and manufacturer.

File management: Store EPUBs in organized folders:

• Books
• Download
• Cloud folders (when supported)

Modern Android versions use a system file picker, so fixed storage paths are unreliable.

1. Open app settings
2. Select the cloud sync option
3. Choose a supported service
4. Authorize access
5. Select a sync folder when requested

Moon+ Reader supports Dropbox and WebDAV, PocketBook offers PocketBook Cloud, and Librera's F-Droid build does not include Google Drive sync.

External storage: Store large libraries on an SD card:

1. Move EPUBs to the SD card
2. Open the reader app
3. Select the SD card through Android's system picker
4. Add the folder to the library
