X has rolled out a completely rebuilt Android app after nearly a year of development, replacing its legacy foundation with a modern Kotlin and Jetpack Compose stack designed to improve speed, reliability, scrolling, loading and notifications.
TL;DR
- X has rebuilt its Android app from the ground up after a year-long engineering effort.
- The new app uses Kotlin and Jetpack Compose and promises faster loading, smoother scrolling and more reliable notifications.
- The overhaul also gives X a cleaner foundation for shipping future Android features more quickly.
X Rebuilds Its Android App From The Ground Up
X has begun rolling out its newly rebuilt Android application, completing what Head of Product Nikita Bier described as one of the company’s largest engineering projects.
The company said the app was rewritten from scratch rather than refreshed through a conventional update. The new version replaces an older mixed codebase with a modern Android stack built around Kotlin and Jetpack Compose.
That technical shift is intended to make the app faster and easier to maintain. X says Android users should notice improvements across loading, scrolling, notifications and general reliability.
What X Said About The Rebuild
“We’ve completely rebuilt the Android X app from the ground up,” X Engineering said in its announcement. “It’s faster, smoother, and more reliable than the old version in every way.”
The company added that it had modernized the app’s foundation so everyday interactions, including scrolling, loading and receiving notifications, would feel better.
Bier emphasized that the rebuild was not only about fixing current performance issues. He said the new app is “faster, smoother and more reliable,” but most importantly, it will allow X to “build new features at lightning speed.”
What Is Changing For Android Users?
The most visible changes focus on speed and consistency. Users should experience quicker loading times, smoother movement through timelines and conversations, and fewer interruptions caused by unreliable notifications or slow interface responses.
The new architecture should also reduce the technical burden on X’s engineering teams. A cleaner codebase can make it easier to diagnose bugs, improve compatibility and release updates without repeatedly working around older software components.
For users, that could mean Android-specific fixes and features arrive more quickly than before. It may also help X narrow the experience gap between its Android and iOS applications, an issue that users have raised over the years.
More Android Improvements Are Planned
The rebuild does not mark the end of X’s Android work. Reporting around the launch indicates that the company still plans to improve performance on older devices and expand support for features that are not yet fully available on Android.
These planned additions include hosting Spaces, stronger video editing tools and video reactions. X has also suggested that some future capabilities could appear on Android before reaching other platforms.
That would represent a notable change in how the company approaches Android development. Instead of treating the app as a slower-moving companion to its iOS version, X now has a dedicated technical foundation that can support faster experimentation.
Why The Rebuild Matters To X
Android has a major presence across international smartphone markets, making the quality of X’s Android app important to user growth, engagement and retention.
By replacing its legacy code rather than continuing to patch it, X is making a long-term investment in its mobile platform. The immediate result is a faster and more reliable app, while the broader objective is to create a foundation that supports quicker feature development in the years ahead.
