Send to X4: E-Ink Companion

Chapiware

About this app

Your all-in-one companion for the Xteink X4 e-ink reader. Send articles, notes, custom screensavers, and EPUB files — all over WiFi, with zero cloud accounts.

• ARTICLES TO EPUB IN SECONDS Paste any URL or tap Share from your browser. Send to X4 strips ads and clutter, then converts articles into clean EPUBs optimized for e-ink. Supports threads, long-form content, and image-rich pages. Queue multiple articles and batch-send them all at once — even pre-download them for offline sending later.

• IMPORT YOUR OWN EPUBs Already have EPUB files? Pick them from your device and send them straight to the X4. No conversion needed.

• QUICK NOTES Type or paste any text and send it to your X4 as a .txt file. Perfect for meeting notes, to-do lists, or reading lists. Drafts are saved automatically.

• SLEEP SCREEN DESIGNER Create your own lock screen with the built-in editor. Add text, images, and freehand doodles. Use the Sign mode for full-screen to-do lists that auto-size to fill the display. Enable "Overwrite Default" to always replace the same file — your X4 lock screen becomes a living to-do list.

• >1,000+ E-INK WALLPAPERS Browse curated wallpapers from x4ePapers (lowio.xyz and readme.club). Preview, send, or try a random pick. New wallpapers added regularly.

• PHOTOS TO SCREENSAVERS Pick any photo from your gallery. It is automatically cropped, resized, and converted to a 480x800 BMP ready for the X4 display.

• DEVICE FILE MANAGER Browse articles, notes, and screensavers already on the device. Preview sleep screen thumbnails. Swipe to delete files you no longer need.

• 100% PRIVATE Everything transfers over local WiFi. No cloud. No accounts. No tracking. Your data stays between your phone and your X4.

• WORKS WITH ALL FIRMWARE Full support for both Stock and CrossPoint firmware. Configurable IP, custom storage folders, and optional date-based subfolders to keep everything organized.

Ratings and reviews

I recently purchased an XTEINK: X4 (a small ereader with minimal features) and this is a great companion app. It allows you to do a wide range of file transfers to the device with just a regular wifi connection.

update - working great now, thanks! Doesn't work. thanks for releasing this, but unfortunately doesn't work on my device (whilst able to use the Firefox plugin, and crosspoint.local via browser.

Sweet App! Works pretty seamlessly. I hope it is updated to handle the X3 as well which has slightly different resolution.
