It transfers and synchronizes ebooks (and screensaver images) from your Android phone to a Kindle running KOReader, over Wi-Fi (SFTP). No cable, no cloud — everything stays on your local network.

KEY FEATURES
• Library sync: compares your phone's ebook folder with the Kindle's and uploads what's missing. Optional two-way mode (also downloads books that are only on the Kindle).
• Quick send: send individual files, or use "Share → KOReaderSync" from any app.
• Network scanner: finds your Kindle automatically (SSH port) — no need to hunt for the IP address.
• Custom screensavers: upload your own images to the Kindle's screensaver folder.
• Formats: EPUB, PDF, CBZ/CBR, MOBI, FB2, DjVu, TXT and more (handled by KOReader).
• Modern Material Design UI, light/dark theme.
• Multilingual: English, Italian, Spanish, French, German.
• Built-in guide.

HOW IT WORKS
On KOReader (on the Kindle) start the built-in SSH server (Menu → Tools → SSH Server) and connect to Wi-Fi. In the app, tap "Scan network" or enter the IP, then sync. Books are stored in /mnt/us/Books on the Kindle.

REQUIREMENTS
• A jailbroken Kindle running KOReader, with the SSH server enabled.
• Phone and Kindle on the same Wi-Fi network.
Note: this app does NOT jailbreak your Kindle and won't do it for you — you need a Kindle already set up with KOReader.

PRIVACY
No data collected. No ads, no tracking, no accounts. Your settings stay only on your phone; files go directly to your Kindle on the local network, never to external servers ## Rankings - #3,066,983 — Overall ## Permissions and access ### Permissions - `android.permission.INTERNET` - `com.android.vending.CHECK_LICENSE` - `com.piero.koreadersync.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Similar extensions and apps - [ブックスKOZUCHI](https://chrome-stats.com/d/com.sanwaco.bookskozuchi) - [Calibre Ebook Reader - CaliMob](https://chrome-stats.com/d/com.dm_devs.calimob) — 8,232 users - [KReader PRO](https://chrome-stats.com/d/com.hk.ebooks.pro) — 2,873 users, 3.62 / 5 - [Vintage Reader - Ebook Reader](https://chrome-stats.com/d/com.vigilsoftware.vintagereader) — 398 users - [PocketBook reader - EPUB, PDF](https://chrome-stats.com/d/com.obreey.reader) — 10,732,009 users, 4.19 / 5 - [Koodo Reader](https://chrome-stats.com/d/com.koodoreader.expo) — 3,650 users - [Quick Reader](https://chrome-stats.com/d/com.maxlo.quickreader) — 18 users - [KReader - kindle read Ebooks](https://chrome-stats.com/d/com.hk.ebooks) — 296,439 users, 3.20 / 5 - [Link2Read - Send to E-reader](https://chrome-stats.com/d/com.link2rest.app) — 94 users - [to kindle](https://chrome-stats.com/d/com.tokindle) — 8,166 users - [Quick Reader ~ Free Version](https://chrome-stats.com/d/com.maxlo.quickreaderfreeversion) — 50 users - [JetReader](https://chrome-stats.com/d/net.erlenddahl.jetreader) — 25 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.piero.koreadersync)
