## What is FolioLink?

FolioLink is the iPhone companion for e-readers running Folio, the open-source firmware for the Xteink X4 Pro. Open the app and everything your reader has collected is already here.

READING STATISTICS
• Daily goal, streaks and a reading calendar
• Weekly charts and reading by time of day
• A review card for today, this week, month, year or any period you choose

LIBRARY
• All books on your reader with their progress
• Statuses — want to read, reading, finished — and shelves that sync back to the reader

HIGHLIGHTS AND VOCABULARY
• Highlights you make on the reader, with chapter, position and your notes
• Every word you looked up in the reader's dictionary, with its context
• Export highlights to Markdown

SLEEP SCREENS
• Design dashboard and quote sleep screens and send them to the reader

YOUR READER, FROM YOUR PHONE
• Send books, web articles and fonts over Wi‑Fi
• Change reader settings and save reader screenshots to Photos
• Install signed firmware updates, confirmed on the reader itself
• Changes made away from the reader wait in a queue and are sent when it connects
• Optional background sync over Bluetooth

PRIVATE BY DESIGN
No accounts, no ads, no analytics. FolioLink talks only to your own reader on your local network or over Bluetooth, and pairing with a PIN makes sure nobody else on the network can change it.

FolioLink requires an e-reader running the Folio firmware (github.com/guloff/folio-firmware). FolioLink is an independent project and is not affiliated with Xteink.
