Performance is our top priority, glad to hear our efforts appreciated! More improvements to come
Rewriting the 𝕏 Android app was also a big deal. It was really bad for such a long time.

Working on some cold start improvements for the New X Android (already live for alpha users)
Hi X Android folks! If you're on version 12.20+, you're now running the latest iteration of our new Android app. For context: for the last 8 months we were shipping two apps in a single binary, and that introduced some perf overhead. But shipping two apps in one was needed to make the switch to the new experience as smooth as possible for everyone. With 12.20+ that overhead is gone. We ship a single app, built entirely on the new shiny kotlin + compose codebase. This resulted in: • 33% smaller app binary size • 69% faster app startup • Got rid of 3.15M lines of code from the OG app What's next: we hear you on performance. It's our main focus right now - scroll smoothness, battery, networking and memory - and there's more coming. Thanks for the patience and the feedback along the way - keep it coming!

Anyone got the 12.20.4 version of the app? WDYT?
After 13 years, this is my last week at X. So proud to be a part of the team that builds this incredible platform. X is the only place in the world that gives everyone a voice in the global town square. Behind the app is an insanely talented team of engineers and staff who work 24/7 to make it better. I couldn’t be more grateful to have gotten to work so closely with them. Especially the last few years building under pressure most companies will never know. From stabilizing core systems to rebuilding DMs and live-streaming, every day I learned something new from brilliant people. Thank you to everyone who helped me out along the way. 💙🖤

Since the roll out we were working hard to deliver new functionality and catch up on feature parity with iOS and add things that never existed before. Here are some features we are currently rolling out.

Ladies and gentlemen, it's time to pass the torch and demote myself to my natural state: a poster. I'll be stepping back from leading product for 𝕏 and will continue on as an advisor. Serving the X community has been the privilege of a lifetime. X is, and will remain, the most important communication technology in history. But running this app is a 24/7 job and it's now time for me to take a breather. The app is seeing unprecedented growth in new users & engagement. We continue to break records every month. We've climbed 70 spots in the App Store since this time last year. And in the last 400 days, we rebuilt almost every aspect of X: the Timeline, the Android app, onboarding, notifications, chat and more. We also launched nearly 30 new products while protecting the integrity of the town square: becoming the first app to show Country-of-Origin on profiles and mounting defenses against AI bots. There's certainly much more work to be done, but our foundation is stronger than ever. None of this would have been possible without the incredible team here. The next leaders will take X to even greater heights with @benjitaylor on design, @singhai on core product engineering and @dinkin_flickaa on mobile engineering -- among many other great people. Thank you to Elon and the X team for welcoming me into the company. See you on the Timeline.

X app now feels better on Android. I don't know exactly how but the experience is better, the interactions look more smooth. The colors, the effects, are way more better.
