CrossX - Send To X4

CrossX Send turns any web page into a clean, formatted EPUB e-book and sends it directly to your Xteink X4 e-reader over its local WiFi hotspot. No cloud. No accounts. No subscriptions. Everything stays on your network.

CONVERT ANY WEB PAGE

Paste a URL, tap one button, and get a beautifully formatted EPUB in seconds. The app automatically fetches the page, extracts the article content, strips out ads, scripts, and clutter, and builds a standards-compliant EPUB 2.0 file. Long articles are automatically split into chapters. Twitter/X posts are fully supported.

WORKS OFFLINE

Don't have your e-reader nearby? No problem. Convert articles anytime — they're automatically queued and sent the moment your device connects. You'll get a prompt as soon as the X4 is detected.

CONVERT FROM ANYWHERE

Use the iOS Share Extension to convert pages directly from Safari — no need to open the app. Or set up a Siri Shortcut to convert pages with your voice or from any app's Share menu.

FILE MANAGER

Browse your X4's storage, upload files (.epub, .xtc, .bump, .txt), create folders, move files between directories, and delete what you don't need. Everything is managed over WiFi with real-time upload progress.

WALLPAPERX

Set a custom wallpaper on your e-reader. Pick any image from your Photos library, then fine-tune it with controls designed for e-ink: fit mode, 9-point alignment, rotation, color depth (24-bit to 1-bit), grayscale, and invert. Preview exactly how it will look before sending.

DEVICE AUTO-DETECTION

CrossX Send automatically finds your X4 and determines whether it's running Stock or CrossPoint firmware. Just connect to your e-reader's WiFi and tap Connect. Supports mDNS/Bonjour discovery and static IP fallback.

ACTIVITY HISTORY

A unified timeline tracks every conversion and file operation. Filter by conversions, file activity, or queued items. Tap any entry for full details. Swipe to resend or delete.

PRIVACY FIRST

Zero data leaves your local network. No cloud services, no analytics, no tracking, no accounts. Your reading habits are yours alone.

NATIVE ON iPHONE, iPAD & MAC

A single app delivers a truly native experience on all three platforms — not a web wrapper, not Mac Catalyst. Designed with the latest Apple technologies including Liquid Glass, SwiftUI, SwiftData, and App Intents.
