X Launches Rebuilt Android App After Year-Long Engineering Overhaul
Elon Musk's X rolls out a ground-up Android rewrite, addressing years of platform neglect with performance improvements and faster feature velocity.
Last verified:
X shipped a fully rebuilt Android application on July 20, following nearly a year of engineering work. The platform’s new app is constructed from scratch using Kotlin and Jetpack Compose, addressing a widening gap between Android and iOS user experience that had persisted since Musk’s 2022 acquisition.
Ground-Up Reconstruction and Performance Gains
According to TechCrunch, the new Android version promises improvements across core interactions: scrolling responsiveness, message loading, and notification reliability all received engineering attention. X’s engineering team described the effort as “one of the largest engineering projects” in the company’s history, per head of product Nikita Bier. The scale of the rebuild reflects the technical debt accumulated over years of Android neglect—the platform had become so degraded that the app previously failed to load posts when users tapped external links.
Accelerating Feature Deployment
Bier framed the modernized codebase as a foundation for faster feature velocity. X has been rolling out new products—X Money and X Chat received standalone applications earlier in 2026—and the rewritten Android stack is designed to remove architectural friction around expanding this feature set. Bier stated the rebuild will enable the team to “build new features at lightning speed.”
Incomplete Feature Parity and Rollout Timeline
The July 20 release does not achieve full feature parity with iOS. According to TechCrunch, Spaces (X’s live audio feature) support and performance optimization for older Android devices remain in development. The company plans to add video editing, react-with-video functionality, cashtags, and custom timelines in subsequent updates. Existing Android users can download the new app through the Google Play Store.
Why This Matters
Android commands roughly 72% of global smartphone market share, making platform neglect a direct revenue headwind in emerging markets where iOS adoption is significantly lower. The rebuilt app signals X’s intent to re-engage users who abandoned the platform during years of degraded Android performance. If the modernized codebase delivers the promised reliability gains, it may lower the barrier to feature launches—a competitive advantage against rivals like Bluesky and Threads, which have invested in native cross-platform development from inception. The success of this rebuild will likely determine whether X can reverse Android market-share losses accumulated since 2022.
Frequently Asked Questions
Was the Android app rewritten using AI tools?
According to X's Grok account, the full Android rewrite was completed by X's human engineering team using Kotlin and Jetpack Compose, with no disclosed reliance on internal AI for the codebase.
What features are still missing from the new Android app?
According to X head of product Nikita Bier, Spaces (live audio) support and optimizations for older Android devices are still in progress, along with video editing and react-with-video functionality coming soon.
Why was this Android rebuild a priority?
TechCrunch reports that X saw one of its largest Android download weeks in October 2025, and the old app had critical issues—at one point, it could not load X posts when users clicked links.
