X has officially launched a completely rebuilt version of its Android application, marking what the company's Head of Product, Nikita Bier, described as "one of the largest engineering projects in the company's history." The redesign aims to deliver a significantly improved user experience, addressing long-standing performance disparities between the Android and iOS versions of the app.
Addressing Past Performance Challenges
In 2025, X acknowledged that its Android app lagged behind its iOS counterpart in areas such as performance, stability, and feature parity. This recognition spurred a major initiative to overhaul the Android experience from the ground up. The company assembled a dedicated "dream team" of Android engineers to undertake this ambitious rebuild, prioritizing a smoother and more reliable platform for its substantial Android user base.
Key Improvements and Technical Foundation
The new X Android app promises a noticeable boost in performance across the board. Users can expect:
- Faster Loading Times: Content will load more quickly, reducing wait times.
- Smoother Scrolling: The app's interface will feel more fluid and responsive during navigation.
- Enhanced Reliability: Improved stability means fewer crashes and a more consistent experience.
- Better Notifications: Stability enhancements have been applied to the notification system.
Under the hood, the application has been rewritten on a modern Kotlin + Jetpack Compose foundation. This new codebase is designed not only to improve current performance but also to make the app easier to maintain and enable faster development of new features in the future. Bier emphasized that this is not just a regular update but a fundamental modernization of the app's core architecture.
Global Rollout and Future Features
The rebuilt X Android app is now rolling out globally and can be updated through the Google Play Store. While the initial release focuses on core performance and stability, X has confirmed that several features are still under active development, including Hosting Spaces, performance optimizations for older Android devices, a Video Editor, and the ability to React with Video. The new architecture is expected to accelerate the integration of these and other upcoming functionalities.
