KOReaderSync

KOReaderSync gets your ebooks from your phone to your Kindle, wirelessly. 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
