X finally ships its rebuilt Android app

X has officially rolled out a rebuilt version of its Android app, following through on a project the company first teased roughly a year ago.

This Tweet is currently unavailable. It might be loading or has been removed.

In an August 2025 post on X, Head of Product Nikita Bier announced he was recruiting what he called the "Android Dream Team," describing the effort in characteristically hyperbolic terms and asking engineers to help "rebuild the X Android app" from the ground up. The recruitment push came as users had periodically flagged bugs and performance issues with the app in the months since; for instance, tapping tweet links from other apps, like WhatsApp, would incorrectly load the main timeline instead of the intended post.

Nearly a year after Bier's initial call for engineers, Bier announced on July 20 that the rebuild was complete, calling it one of the largest engineering projects in the company's history. He described the new app as faster, smoother, and more reliable, and said the updated foundation would let the team ship new features more quickly going forward.

An X spokesperson elaborated on the changes in an email statement to Mashable: "X modernized the foundation so everything is faster, smoother, and more reliable, including scrolling, loading, and notifications."

Beyond the underlying performance improvements, the update doesn't appear to introduce new user-facing features at launch. The company is framing this release as an infrastructure overhaul, with the spokesperson reiterating that Bier's posts on X, including support for hosting Spaces and better performance on older devices, are expected in future updates.
