CrossInk for XTEINK X4 Pro! A lot of cool things available

 

CrossInk Beta Transforms the XTEINK X4 Pro: Gestures, Offline Sync, and Library Support

The e-reader market is crowded, but true power users know that hardware is only half the battle. The software running on your e-ink device dictates whether it is a seamless reading companion or a frustrating paperweight. For owners of the XTEINK X4 Pro, the newly released CrossInk beta firmware is proving to be a massive leap forward. Pushing the boundaries of customization, gesture control, and offline capabilities, this firmware update effectively turns the X4 Pro into an entirely new device. Whether you are using it alongside a premium color display or as your standalone workhorse, CrossInk unlocks features that standard e-readers simply cannot match.



Key Upgrades at a Glance

The Best of Both Worlds: Granular Touch and Tactile Control

One of the most pervasive dilemmas with modern e-readers is the touch screen itself. While essential for navigation, touch displays often lead to accidental page turns when you are just trying to hold the device comfortably. The CrossInk firmware introduces an elegant solution: the ability to turn off the touch display entirely, allowing the X4 Pro to operate strictly via its physical buttons, much like the standard non-touch X4.

However, the true genius lies in its granular customization. Users can disable general touch sensitivity while keeping specific swipe gestures active. This means you can grip the device naturally, completely immune to stray taps, but still use a deliberate thumb swipe to turn the page. Furthermore, every physical button is fully reprogrammable. Want to use a short press of the power button to instantly toggle your front light on or off? With CrossInk, assigning that shortcut takes just a few seconds.

Smart Reading Tools and Seamless Annotations

An e-reader is only as good as its reading tools, and CrossInk brings a suite of powerful utilities right to your fingertips. Long-pressing a word instantly summons a comprehensive, multi-page dictionary—such as Cambridge—which you can easily dismiss with a quick swipe.

Highlighting, referred to in the ecosystem as "clippings," is also receiving a smart overhaul. While dragging a finger across an e-ink screen to highlight text can occasionally feel fiddly due to the screen refresh rates, CrossInk offers a highly precise alternative. By simply tapping the first word and the last word of your desired passage, the software instantly creates a clean, accurate clipping. You can easily access these clippings, along with bookmarks and global settings, through a dedicated swipe-up menu or custom gestures like a double-tap for the home screen.

True Offline Independence and Peer-to-Peer Syncing

Perhaps the most futuristic addition in the CrossInk beta is its approach to device syncing. Typically, keeping your reading progress updated across multiple devices requires a steady Wi-Fi connection and a cloud server. CrossInk introduces a "nearby position sync" feature that completely bypasses the internet.

Using a direct peer-to-peer connection, you can sync your exact reading location—or even transfer an entire book file—between two CrossInk-enabled devices. You could be sitting in a remote cabin in the woods with zero mobile connectivity, and your XTEINK devices will still seamlessly communicate with each other.

The Verdict

While still in its beta phase, the CrossInk firmware for the XTEINK X4 Pro is already polished enough to serve as a daily driver. It is a shining example of how open, highly customizable software can elevate e-ink hardware from a simple reading tablet into an absolute powerhouse tailored precisely to the reader's habits.
