Expo

🥳 Observe is now generally available! React Native startup and per-screen performance from real devices, with every build and OTA update marked on the chart. Now you can see how your app actually feels to your users. Details in today's blog from @kadi.bsky.social: try.expo.dev/observe-ga-b...

Announcing the 2026 𝝠 Expo App Awards 🙌 The talent, the care, and the craft we see in the Expo community is staggering. The 𝝠 Expo App Awards is a celebration of the apps and the people who build them. Submission criteria is simple: if your app uses Expo, submit it. expo.dev/awards/2026

The power of 𝝠 Expo + LLMs is staggering. Nathan Schroeder built this app a day. It's called Amber and it's a place to save almost anything and let AI organize it all for you. Built on Expo + Convex + Clerk + AI SDK.

🙌 Expo SDK 58 beta is out, built for iOS 27 on React Native 0.88 RC. ◆ 𝚎𝚡𝚙𝚘-𝚊𝚙𝚙-𝚒𝚗𝚝𝚎𝚗𝚝𝚜 puts your app in Siri ◆ @𝚎𝚡𝚙𝚘/𝚊𝚐𝚎𝚗𝚝-𝚌𝚕𝚒 is built for coding agents ◆ Expo Modules 2.0 in beta ◆ Android builds about twice as fast 𝚗𝚙𝚡 𝚎𝚡𝚙𝚘 𝚒𝚗𝚜𝚝𝚊𝚕𝚕 𝚎𝚡𝚙𝚘@𝚗𝚎𝚡𝚝 --𝚏𝚒𝚡 expo.dev/changelog/sd...

Nearly three out of four desktops in the world are not Macs. @keith.bsky.social ran an iOS Simulator with Fast Refresh on a Windows on ARM laptop, a machine that can't run Android Studio either. The phone was a browser tab the whole time 🤯 expo.dev/blog/build-i...

Set up @posthog.com in your Expo app with one command. 𝚎𝚊𝚜 𝚒𝚗𝚝𝚎𝚐𝚛𝚊𝚝𝚒𝚘𝚗𝚜:𝚙𝚘𝚜𝚝𝚑𝚘𝚐:𝚌𝚘𝚗𝚗𝚎𝚌𝚝 ◆ Org, project, SDK, and env vars in one shot ◆ Every event tagged with its EAS update ◆ Workflows that hold a rollout until errors clear expo.dev/changelog/po...

Expo Modules 2.0 is here in preview. Your module is an annotated Swift class. That's the whole API. It's also up to 14.5× faster than SDK 55. iOS today in SDK 57, Android next, official beta in SDK 58 ↓ expo.dev/blog/an-earl...

🍁 ATTN: Maple Mobile Devs! We're hosting a build session in Toronto this Wednesday. Bring your apps and we'll work on your submissions to Shipaton. www.creativeblocks.club/events/deb7c...

It uses EAS Simulator by @expo, which gives your background agents access to on-demand cloud iOS simulators, so they can verify their work and achieve better results 👀📈 EAS Simulator is in closed preview - join the waitlist if you are interested expo.dev/services/sim...

We think apps should fix their own bugs. TestFlight feedback comes in. An agent reproduces it, files the issue, writes the fix and runs it on a simulator before opening the PR. Our Cloud Simulators service is in preview. Here's the waitlist if you want to try it: https://try.expo.dev/agentic-dev-x

React Native TextInput now has a real paste event. 𝚎𝚡𝚙𝚘-𝚙𝚊𝚜𝚝𝚎-𝚒𝚗𝚙𝚞𝚝 wraps your existing input and fires 𝚘𝚗𝙿𝚊𝚜𝚝𝚎 with text or local file URIs. Images, GIFs, screenshots, iOS stickers. 𝚗𝚙𝚡 𝚎𝚡𝚙𝚘 𝚒𝚗𝚜𝚝𝚊𝚕𝚕 𝚎𝚡𝚙𝚘-𝚙𝚊𝚜𝚝𝚎-𝚒𝚗𝚙𝚞𝚝 ✍️ @arunabhverma.com expo.dev/blog/pasting...

Workshopping a new term: Delegation Engineering 🤷‍♀️ Give your agent the data to find and fix regressions for you. expo.dev/solutions/ex...

Turns out you did not "have to be there" for this one. @kadi.bsky.social's Chain React talk was recorded! Excellent introduction to a new service that measures the performance of your app on real user devices: youtu.be/G9RoD_QpJYQ?...

SWSH's release pipeline: 𝚎𝚊𝚜 𝚋𝚞𝚒𝚕𝚍 on self-hosted runners, signing credentials in EAS, EAS Submit into both stores, an Appium suite gating the release, and Observe watching time-to-interactive after it ships. There's no human sitting between a merge and App Store review. expo.dev/blog/inside-...

Install Observe in one command: 𝚗𝚙𝚡 𝚎𝚡𝚙𝚘 𝚒𝚗𝚜𝚝𝚊𝚕𝚕 𝚎𝚡𝚙𝚘-𝚘𝚋𝚜𝚎𝚛𝚟𝚎 ...or ask an agent to do it.

Are you based in NYC, well, you should join us on Sept 24 for a joint @expo.dev x @infinite.red x Chime meet up. Register here: luma.com/fegsycpl?tk=...

contrary to what might seem reasonable, i think now is an even better time to be building with @expo.dev. live refresh app building was always great, but now with LLMs its doubly amazing. cannot imagine actually building an app with swift or kotlin now tbh

Your Expo app can have a typed, reactive backend before your coffee gets cold. 𝚎𝚊𝚜 𝚒𝚗𝚝𝚎𝚐𝚛𝚊𝚝𝚒𝚘𝚗𝚜:𝚌𝚘𝚗𝚟𝚎𝚡:𝚌𝚘𝚗𝚗𝚎𝚌𝚝 provisions Convex and sets your env vars for local dev and builds in one shot. 𝚞𝚜𝚎𝚀𝚞𝚎𝚛𝚢 updates itself when the data changes. New guest post from @convex.dev: expo.dev/blog/convex-...

Working on something new...stay tuned.

Some nice shots of the beautiful Norbauer mechanical keyboards that were awarded as prizes for the 1st annual Expo App Awards.

Wellspoken went from 400 users to hundreds of thousands of downloads in six months, without the founder ever opening Xcode. Tons of actionable tips and tricks in here for making your apps successful: try.expo.dev/wellspoken-b...

Most AI coding tools are noise. Three actually matter for shipping mobile apps. ◆ Skills: instruction files loaded on demand ◆ MCP: gives the agent hands outside the editor ◆ Context discipline: stay under 50%, branch by task Full guide and video: expo.dev/blog/how-to-...

Some of the most talented builders in our community are sharing their code in our new demos page: expo.dev/demos Check it out and let us know what we're missing.

PrizePicks ships JS same-day, lets native ride its own release train, and the Expo fingerprint routes each change automatically. This is high stakes continuous deployment. labs.prizepicks.com/continuous-d...

Switching off 𝚎𝚡𝚙𝚘/𝚟𝚎𝚌𝚝𝚘𝚛-𝚒𝚌𝚘𝚗𝚜 can cut ~4MB from your app bundle. Just from changing an import. The 𝚛𝚎𝚊𝚌𝚝-𝚗𝚊𝚝𝚒𝚟𝚎-𝚟𝚎𝚌𝚝𝚘𝚛-𝚒𝚌𝚘𝚗𝚜 packages now work natively with 𝚎𝚡𝚙𝚘-𝚏𝚘𝚗𝚝 across Expo Go, dev builds, everywhere. Migration guide → https://try.expo.dev/vector-icons-bluesky

What if AI agents use specs, not just prompts, to build software? Watch @ide.bsky.social, co-founder of @expo.dev, explain linked literate programming, a simple approach that keeps code, specifications, and intent in sync so AI can build more accurate, maintainable software. youtu.be/a8xYFd1ZLNQ

One of my favorite things about the Demos app is that every update generates a slightly different app icon, so it's always a nice little surprise.

Expo SDK 57 will be the easiest upgrade you've ever made. One command. No breaking changes. And boom, you're on React Native 0.86. It's also the first step toward a new release cadence we're considering: optional, non-breaking upgrades between the big SDKs: try.expo.dev/bluesky-sdk57

💅 Want to get really good at building apps with AI and Expo UI? @zoontek.me from our SDK team is giving an Expo UI focused talk at the React Native London Meetup on July 16th. Save your seat and tell your friends: guild.host/events/react...

My App.js Conf talk is now live! I had such a great time speaking last month and sharing some of what we’ve learned building Expo apps at Partiful. Huge thank you to @swmansion.com & @expo.dev for having me and to everyone who came by and chatted afterwards. Watch at: youtu.be/swFMxsOWkpk

You already know your company needs a mobile app. The bar for building one is surprisingly low. The hard part is convincing leadership to let you. So we wrote out the case you can bring to them, framed for a "decision maker" type person ↓ expo.dev/blog/how-to-...

We're sharing the formula for making vibe-coded apps look pro. Agents are good at assembling layouts. But they have no eyes, because design is not code. The fix isn't a better prompt. It's a shared vocabulary: 8 principles + a screenshot critique loop. Full framework ↓ expo.dev/blog/how-to-...

Built this little loading animation with Skia + @expo.dev ✨

Trust your instincts. If your app feels slow today, there's probably a cold-start regression on a specific build, on specific devices... this has always been a difficult problem to identify. Now it's not. Our new "Observe" service is in open beta, free up to 10k MAUs. → try.expo.dev/observe-beta...

Recreated this with Skia + @expo.dev today. Inspired by @frboulais.bsky.social ✌️

The fastest mobile build is the one you never run. Expo's CI/CD Workflows skips the full build when your native layer hasn't changed. We compared it honestly against Bitrise, Codemagic, GitHub Actions, and CircleCI for 2026. We're biased, but fair. try.expo.dev/mobile-cicd-...

iOS builds in SDK 56 are faster out of the box. Expo modules now ship as precompiled XCFrameworks, so they link instead of compiling from source on every build. No config, no migration steps. Full nerd sniping eng blog from @chrfalch.bsky.social right here: try.expo.dev/precompiled-...

Expo SDK 56 ships a Kotlin compiler plugin that removes reflection from Android module startup. 70% faster module init. 30% faster first render. 6× faster Records. App developers get the gains automatically. Module maintainers: one annotation. try.expo.dev/kotlin-compi...

𝚎𝚡𝚙𝚘/𝚟𝚎𝚌𝚝𝚘𝚛-𝚒𝚌𝚘𝚗𝚜 is moving to deprecated. The 𝚛𝚎𝚊𝚌𝚝-𝚗𝚊𝚝𝚒𝚟𝚎-𝚟𝚎𝚌𝚝𝚘𝚛-𝚒𝚌𝚘𝚗𝚜 packages now work directly with expo-font, so there's no reason for the wrapper anymore. Run the codemod and you're down ~4MB with a cleaner setup. It's a bit of effort. But it's worth it. try.expo.dev/vector-icons...

Your native modules got 2x faster in SDK 56. No code changes required. try.expo.dev/jsi-blueksy

Wait... You can paste Apple Stickers directly into an @expo.dev app 🤯 Added support for this in expo-paste-input. Open source ↓ github.com/arunabhverma/expo-paste-input

📱 Applied Expo UI Intermediate Workshop Join Keith Kurak ( @expo.dev) & Frank Calise's workshop on Expo UI in React Native. Use SwiftUI + Jetpack Compose bindings in React, & learn when to use native UI vs cross-platform. We’ll cover Expo Router transitions + Android colors. chainreactconf.com

Swift now talks to JSI directly in Expo SDK 56. The Objective-C++ layer is gone. A native call that crossed three languages now lowers straight to C++. ◆ 1.6 to 2.3x faster ◆ Beats Turbo Modules on async (1.55x) ◆ Ships as a prebuilt xcframework try.expo.dev/jsi-blueksy

My personal hero James Ide from @expo.dev presenting about linked literate programming. So thrilled to be at @cascadiajs.com for this !!

If you've ever felt uneasy for 24 hours after you shipped a new build - watch @kadi.bsky.social's talk. You'll feel better. We timestamped it for you: www.youtube.com/live/dvpeMlw... We opened the beta for our observability service today and we need feedback. Try it: try.expo.dev/observe-beta...

🚀 Expo Router v56 is the biggest update since it originally launched. ◆ Forked the React Navigation internals ◆ Streaming SSR + 𝚐𝚎𝚗𝚎𝚛𝚊𝚝𝚎𝙼𝚎𝚝𝚊𝚍𝚊𝚝𝚊 ◆ Android toolbar (left, right, bottom) ◆ Native Tabs gains 𝚍𝚒𝚜𝚊𝚋𝚕𝚎𝚍 Many more highlights in the blog: try.expo.dev/router-56-bl...

Where did you go Expo Go? A lot of you have been asking...so we made a video to explain the status of Expo Go: youtu.be/bu8X9mCL0Ek?...

Expo UI now runs callbacks on the UI thread. SDK 56 ships worklet integration for @expo/ui. SwiftUI and Compose components update shared state synchronously, no JS hop. Flicker-free input masking, finally 😅 Full blog from @nishan.dev: try.expo.dev/worklets-blu...
