Following the international launch of the AI InkApp Store, XTEINK brings new reading, productivity, and entertainment features to its compact magnetic E Ink reader.

Diamond Bar, CA, United States, 6th Nov 2026 – XTEINK has introduced its AI InkApp Store to international markets, expanding the software capabilities of its magnetic E Ink devices. The XTEINK X4 Pro, the first model to support the platform, is gaining new lightweight applications that bring additional functionality to its pocket-sized design. The latest additions include PocketPets, To Do List, Sudoku, and Clock Wallpapers, offering new ways to enjoy reading, stay organized, and make use of the device throughout the day. Rather than turning the X4 Pro into another smartphone, the update builds on its original purpose as a portable e-reader, introducing practical features that complement the reading experience.

Featuring a 4.3-inch E Ink display and a compact magnetic design, the XTEINK X4 Pro is built for reading on the go. Its small form factor makes it convenient to carry during commutes, travel, or everyday outings, offering a dedicated reading experience without the distractions commonly associated with smartphones. With an expanding collection of Ink Apps, the device is also becoming more useful between reading sessions, bringing simple tools and entertainment into a screen originally designed for books.

New E Ink Apps Bring More to Everyday Reading

Among the new applications, PocketPets introduces a virtual companion that grows alongside the user’s reading progress. As reading time accumulates, the digital pet develops, turning everyday reading into a more rewarding experience. For those hoping to build a regular reading habit, it adds a playful sense of progress without changing the familiar pleasure of spending time with a book. The To Do List app brings a different kind of practicality to the X4 Pro, providing a simple place to organize daily responsibilities, manage personal plans, and check off completed tasks. Whether keeping track of shopping lists, study schedules, or work priorities, users can manage small everyday tasks directly on their E Ink reader.

For moments away from books, Sudoku brings classic number-based puzzles to the E Ink screen, offering a relaxing way to enjoy short breaks or quiet moments during the day. Clock Wallpapers, meanwhile, give the device another purpose when it is not being used for reading. With time and date displays presented in different visual styles, the X4 Pro can double as a minimalist desk clock, fitting naturally into a workspace, bedside table, or reading corner. Together, these lightweight applications add variety to the device while preserving the simplicity that makes a pocket e-reader appealing.

Portable Design Meets an Expanding Software Ecosystem

The X4 Pro’s appeal begins with its portability. While larger e-readers are often carried in bags, a pocket-sized magnetic E Ink reader offers a convenient alternative for people who want to read throughout the day. Its compact design makes it easy to incorporate reading into short breaks, commutes, and travel, while the new applications extend its usefulness beyond those moments. A user might spend a few minutes reading during a morning commute, check a task list later in the day, or leave the device displaying the time on a desk. These small additions allow the X4 Pro to serve different everyday needs without moving away from its identity as a dedicated reading device.

Supporting this expanding functionality is XTEINK’s recently launched AI InkApp Store, which brings together application distribution, an open API, on-device runtime, and AI-assisted development tools. The platform includes InkApp AI Studio, where natural-language descriptions can be translated into application code, providing developers and technology enthusiasts with additional opportunities to explore personalized software for compatible E Ink hardware. For X4 Pro owners, the broader value lies in access to a growing collection of applications and the potential for future software updates. The InkApp ecosystem currently supports the X4 Pro, with compatibility for the X4 Classic planned for a future update.

Available in Space Black and Mist Gray, the XTEINK X4 Pro has a manufacturer’s suggested retail price of $99. By combining portable reading hardware with an expanding software ecosystem, XTEINK is giving its pocket e-reader more ways to fit into everyday life, keeping books at the center of the experience while adding practical uses for the screen between reading sessions.
