This tiny, magnetic e-reader could stop you from doomscrolling

A new breed of e-readers is emerging, leveraging MagSafe technology to integrate seamlessly with smartphones, potentially curbing the addictive behavior of doomscrolling. The Xteink X3, a compact e-ink reader, attaches to the back of a phone via a Pop Socket-like mechanism, providing a dedicated reading experience that minimizes distractions. By decoupling reading from the phone's screen, this design may help users break the cycle of endless scrolling. AI-assisted, human-reviewed.

The Xteink X3 is a compact, MagSafe-compatible e-ink reader that attaches magnetically to the back of an iPhone, designed to offer a dedicated reading experience and potentially reduce doomscrolling. Priced at $80, the device has a 3.7-inch screen and uses a magnetic charger (no USB-C port), unlike the larger X4 model. The X3 ships with clunky firmware, but a community-made, free, open-source alternative called CrossPoint is available and relatively easy to install with online instructions.

What it does

The X3 magnetically attaches to the back of a phone like a Pop Socket. It can also be carried in a pocket or purse. The device holds hundreds of books via .epub files transferred over Wi-Fi from a phone or computer. It has no apps, no touch screen, and no internet browser — it is a "dumb" e-reader. Users can add custom screensavers.

Tradeoffs

Charging: The X3 uses a proprietary magnetic charger, not USB-C. Battery life is excellent — after two weeks of consistent use, charge dropped from 100% to 96%.
File compatibility: The X3 cannot legally read library ebooks from Libby or books from Amazon's Kindle store, because those use protected file formats. Users must load unprotected .epub files, such as public-domain books or files created with Calibre.
Firmware: The stock firmware is clunky but functional. The CrossPoint open-source firmware is a significant improvement and is free.
Size: The X3 fits standard-sized iPhones (tested with iPhone 16). The previous X4 model only fit larger phones like the iPhone Pro Max.

When to use it

The X3 is best for reading in short bursts — waiting in line, on public transit — as an alternative to opening social media. It does not replace a Kindle for long-form reading or library borrowing. The device requires some manual file management and a willingness to use open-source firmware for the best experience.

Bottom line

The Xteink X3 can help you read more if you make a conscious effort to use it. It is not a magic fix for doomscrolling, but it provides a distraction-free reading option that fits in a pocket. The lack of Libby and Kindle support is a real limitation, but the device's simplicity and long battery life make it a useful tool for readers willing to source their own .epub files.

Getting Digital Fairness Right: EFF's Recommendations for the EU's Digital Fairness Act

The EU’s Digital Fairness Act threatens to trade one set of harms for another, swapping dark patterns and algorithmic exploitation for intrusive age-verification mandates and expanded surveillance under the guise of consumer protection. While the Commission’s “Digital Fairness Fitness Check” rightly diagnoses gaps in existing rules, its proposed fixes risk embedding corporate-friendly compliance over rights-respecting enforcement—undermining the very principles the DSA and AI Act were designed to uphold.
