## What is CrossPoint Sync?

CrossPoint Sync is a wireless companion app for the XTEink X4 e-ink reader. Transfer books, manage your device library, and clip web articles — all over your local WiFi network, no cables required.

WIRELESS FILE TRANSFER
Send EPUBs to your e-ink reader over WiFi. Uploads are chunked and streamed over for reliable, fast transfers.

DEVICE FILE BROWSER
Browse the full file system on your e-ink reader directly from your iPhone. Navigate folders, create new folders, delete files, rename files, move files and download books back to your phone. Swipe actions make file management quick and intuitive.

SAFARI WEB CLIPPER
Save any web article for your e-ink reader with the built-in Safari extension. CrossPoint Web Clipper extracts the article text, downloads images, and converts everything into a clean EPUB that's ready to read on your device. Clips sync automatically the next time you open the app.

UPLOAD QUEUE
Queue multiple books for transfer and watch them upload one by one with real-time progress tracking. The queue persists across app launches — add books now and they'll transfer automatically when your device connects later.

iOS SHARE EXTENSION
Share EPUBs from any app — Files, Safari, email — directly into CrossPoint Sync's upload queue. Files are picked up automatically and transferred to your device.

SLEEP BACKGROUND CUSTOMIZATION
Set a custom sleep screen image on your e-ink reader. Pick any photo from your library, preview it, and upload it to your device as the sleep background.

### 4/5 — Top app but…

*2026-08-11*

The App works great but one issue. It recognize my XTEINK X3 as an X4 for and so it crops the sleeping cover with the wrong resolution, which makes It appear with a letterbox.

### 4/5 — Needs Shortcut Support

*2026-07-26*

Great app but please add shortcut support so it can be used with browsers other than safari

### 5/5 — Great for queuing!

*2026-07-17*

Really nice to be able to send multiple articles or books to the xteink reader throughout the day then just batch upload at once when you open the app and connect the device. It works quite seamlessly.

### 5/5 — Great - Suggestions for features/bugs

*2026-07-03*

Great, works well on my X3. Though I can’t seem to connect via creating a hotspot only via joining my iPhones hotspot, which Is what I use as WIFI on the X3 so I can sync books when I am out and about.

A couple of suggestions: 
- Allow uploading any files into the file system of the X3, so you aren’t limited to only uploading a photo from your library or an ePub. This would allow me to upload .txt files and my own BMPs I’ve already created, as I have the X3 the uploaded backgrounds don’t match as I assume the aspect ratio is made for the X4. My workaround for this is a shortcut I made that converts my photos into a X3 screen sized .BMP file that I upload by putting onto the micro SD card. Allowing for us to freely upload any files (that are supported by the X3) would make things much better. 
- Fix the photo upload so it matches the screen size of the X3 also, or give the option to choose which device you have. 
- if possible, some sort of files integration, not sure if this is possible with iPhones but it would be good to just be able to drag and drop things into the X3 like it’s a USB drive when connected to the phone via the app, though I don’t know if this is possible. 

Thank you for producing this app!

### 5/5 — Ein absoluter Mehrwert!

Ich liebe es einfach! Es macht so spaß die Bücher mit der neuen Software zu lesen. Die App und das damit verbundene File Sharing funktioniert sowohl mit der App, als auch im Browser absolut hervorragend. Es ist super intuitiv und alles ist an seinem Platz. Ich vermisse wirklich überhaupt nichts. Ich danke euch sehr für diese tolle Arbeit!

### 5/5 — Great useful app

*2026-03-27*

Great to see the effort people make to enhance our Xteink reader experience.
There are a few apps now that I have found for the device and they are great.

### 5/5 — Thank you for making this!

*2026-03-19*

An awesome companion to the Xteink with Crosspoint!  I love being able to sync files with my phone, thank you for making this :)

### 4/5 — CrossPoint companion

*2026-03-03*

Very useful, easier to quickly connect (after the first time) than just using a browser. And like the upload progress bar so you know it’s working. Would like to have the ability to move books though so I can archive once finished. 

The article feature is great if you want to use it for longer for articles too.

**Developer response:** Thank you for the feedback. The new update supports moving and renaming books.
