Almost a year ago, Elon Musk-owned X announced that it would begin rebuilding the Android version of its app, which had been underperforming compared to its iOS counterpart. On Monday, the company shipped the updated app, which is now available for download.

X’s new version of Android was built from the ground up and promises improvements to charging, scrolling, notifications and more, X said in its announcement.

The update has been in development for almost a year. Last August, X product manager Nikita Bier said the social media company was forming an Android “dream team” to reshape the experience. Later that fall, he also noted that X had one of its biggest weeks of Android downloads in October, one reason why the new app was a priority for the company.

With today’s launch, Bier described the effort as “one of the largest engineering projects” in the company’s history, saying the new Android app was built from scratch rather than simply updated.

“It’s faster, smoother and more reliable. But above all: it will allow us to create new features at lightning speed,” Bier wrote on X. The Elon Musk-owned social network has been rolling out a number of new features in recent months, including X Money and

The launch of Android could also entice more users in global markets, where Android is the dominant smartphone platform, to download or return to X, after years of abandoning the platform. (The problems on Android were so bad at one point last year that app X couldn’t even load X posts when users clicked on the links.)

However, Bier cautioned that there are still some rough edges to iron out, including improving performance on older Android devices and adding support for Spaces, X’s live audio feature. Those updates are still underway. Bier added that other features, including the new video editor, react with video feature, cash tags, and custom timelines, are also coming to Android soon.

Existing Android users can get the new X app by updating their existing app through the Google Play Store.
