## What is NacreInk?

NacreInk is the companion app for compatible NacreInk E-Ink displays.

Connect over Bluetooth, choose a built-in artwork or one of your photos, apply display-ready styles, and transfer the result directly to your device. The app also supports device naming, battery status, ringing, contacts, firmware updates, image history, and optional AI-assisted image creation for signed-in users.

Images selected from Photos or Camera are processed for the connected E-Ink display. Bluetooth is used to communicate with nearby compatible hardware.
