Description by Jaime Chapinal Written by the developer, not by AppBrain. Click to read.
• 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.
