X has completed one of its largest engineering projects in history: a complete rebuild of its Android app that will let the platform release new features to Android users before iPhone users for the first time. The refreshed application is now rolling out globally through the Google Play Store, marking the end of a development effort that began nearly a year ago.

Why Is X Prioritizing Android Over iPhone?

The shift reflects a strategic recognition that Android powers the majority of smartphones worldwide, particularly across Africa, Asia, and Latin America. By placing Android first in its release roadmap, X can serve a larger share of its global user base without asking them to wait behind iPhone releases. This decision carries particular weight because markets across these regions rely heavily on Android devices, making the platform central to X's international audience.

"The X Android app has been rebuilt from the ground up, allowing future features to reach Android before iOS for the first time as the company speeds up mobile development," said Nikita Bier, Head of Product at X.

The project was about far more than making the app feel faster. X rebuilt the Android application to replace an aging foundation that had become harder to maintain as new features were introduced. The company says the new architecture improves loading times, scrolling performance, notifications and overall responsiveness while creating a cleaner codebase that allows engineers to build and release products more efficiently.

What New Features Are Coming to Android First?

The rebuilt Android foundation is already beginning to change X's release roadmap. Several capabilities are arriving soon for Android users, expanding the platform's focus on video creation, live conversations and personalized content discovery. According to Bier, these incoming features include React with Video, Video Editor and improved Spaces hosting. Other capabilities, including Cashtags and Custom Timelines, are already available, closing feature gaps that had frustrated many Android users.

The Android rebuild arrives as X continues expanding beyond its original social networking roots with investments in creator tools, AI experiences through Grok and newer services such as X Money and X Chat. The rebuilt Android application provides the technical foundation needed to support that broader product roadmap.

How to Benefit From X's Faster Android Development Cycle

• Update Your App Immediately: Download the rebuilt Android app from the Google Play Store to access the latest performance improvements and new features as they roll out, without waiting for iOS releases.
• Explore New Creator Tools: Take advantage of the Video Editor, React with Video, and improved Spaces hosting features designed to enhance content creation and live conversations on the platform.
• Enable Custom Timelines and Cashtags: Use newly available features like Custom Timelines and Cashtags to personalize your content discovery and engage with financial discussions on the platform.

The rollout is not entirely finished. Bier confirmed that engineers are continuing to improve performance on older Android devices and are still completing support for Spaces hosting as feedback from users helps refine the rebuilt application. Even so, completing the rewrite removes one of the biggest obstacles that had slowed Android development.

For users, the immediate benefits are a faster and more reliable app. For X, the larger achievement is creating an Android platform capable of keeping pace with the company's product ambitions while placing Android at the front of future mobile releases. Rather than spending engineering resources working around legacy code, development teams can now focus on shipping new capabilities and refining existing ones.

The decision to prioritize Android reflects a broader shift in how X allocates its engineering resources. In August 2025, Bier announced plans to assemble an Android "Dream Team" to rework the application from the ground up after acknowledging that the Android experience had fallen behind its iOS counterpart. He later pointed to one of X's strongest weeks for Android downloads as further evidence that the platform deserved greater engineering investment. That investment has now resulted in a completely rebuilt application rather than another round of incremental updates.
