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 !!

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...

💅 Expo UI is officially stable in SDK 56. Import from @expo/ui & get SwiftUI on iOS & Jetpack Compose on Android, the real platform components underneath. Read the blog with details for getting started from @kudochien.dev, @nishan.dev, @zoontek.me, @vonovak.bsky.social: try.expo.dev/ui-bluesky

The App Store has over 2 million apps and paid acquisition is up 30% year over year. Meanwhile 65 to 70% of downloads still come from search. If your title, keywords, and screenshots aren't tuned, your app stays invisible. Open-source ASO Skills for your AI workflow: expo.dev/blog/aso-ski...

The CTO of @bsky.app is speaking at our AI Meetup in Seattle this Wednesday. There are way more people registered than we could hope to fit into our space. But we do this meetup once a month so you can just register for next month and expect another awesome lineup: luma.com/p8es4v0t

We weren't planning for Healthcare to become a top Expo vertical. But here we are. 7,200+ health apps shipping on Expo & a big chunk of new signups now come from clinical teams. We're proud of this trend and we built a new page to help health eng teams evaluate Expo: try.expo.dev/healthcare-b...

You need speed. Slow builds kill momentum. We're addressing this from every angle: ◆ Dozens of new M4 Pro/Max Mac Minis added ◆ Compiler caching, Gradle caching, prebuilt binaries ◆ Prebuilt XCFrameworks ◆ Fingerprint workflows so you only build when native code changes expo.dev/blog/build-f...

You can now trigger EAS Workflows with a single HTTP request. New REST endpoint for workflows dispatch. POST your bearer token, app ID, and workflow YAML. Get back the run URL. No CLI. No login flow. Just wire Expo CI into your dashboard, your tool, or your platform.

SDK 56 beta is out 😅 ◆ 50%+ faster iOS builds ◆ 40% faster Android cold starts ◆ Expo UI + iOS widgets now stable ◆ expo-router rebuilt from scratch ◆ Inline native modules + brownfield multi-app support Strong "speed and stability" theme in this one: try.expo.dev/bluesky

Kiril Kostev built an AI video app and got it to both stores in ~1 month. He wrote up the async pipeline, file upload workarounds, polling patterns, and how EAS Build cut days off the timeline. Great read if you're building anything with async AI APIs on mobile: expo.dev/blog/how-to-...

Android builds on EAS are now ~50% faster with Gradle caching. Task outputs get stored and reused between builds. Especially effective for projects with many native modules, where the same tasks repeat across each one. Enable with 𝙴𝙰𝚂_𝙶𝚁𝙰𝙳𝙻𝙴_𝙲𝙰𝙲𝙷𝙴=𝟷 expo.dev/changelog/gr...

When does your React Native animation library actually matter? @appandflow.com benchmarked per-frame UI thread cost across react-native-ease, Reanimated (Shared Values and CSS), and RN Animated. Honest tradeoffs, real numbers, and clear guidance on when it matters. expo.dev/blog/the-rea...

if you're in or near prague, check out the @expo.dev x STRV hackathon this friday (may 1)! 💡 the idea: pick a business that you care about that either doesn't have an app or whose app desperately needs to be replaced, then build the best app you can in a day.

You can now sign into Expo with @github.com. Those of you who have Expo's GH app authorized/installed probably got this email from GitHub. It's very legit. Go ahead and approve the permissions request if you'd like to to sign in with GH (or ignore the email if you aren't interested).

🇹🇷 When FERASET started in late 2022, most mobile engineers in Turkey thought Expo was a prototyping tool. Something for a demo or a hackathon, not production. FERASET saw Expo differently. They went all in...and all the way to #1 on the app store. Here is their story: expo.dev/blog/from-is...

Hipcamp upgraded to React Native New Architecture + Expo SDK 54 in 2 weeks. Original estimate: 2-3 months. Their team built an AI agent to audit 100+ dependencies, handle 40 upgrades for New Arch, and open PRs in parallel. Full writeup from their team: expo.dev/blog/how-hip...

Build real apps. For real businesses. This is the concept for our Hackathon in Prague next week. If you're in Prague & you build apps go ahead and register. We'll be there to support the build process. And we'll provide credits to make sure you aren't blocked by anything. luma.com/Expo_STRV_Ha...

Seth is different. He can zoom out & see all the layers of a problem. He knows what to say. And what to build. And how to build it. What's possibly most impressive is that he delivers all this perspective with warmth and joy. It's infectious. We're lucky to have him! expo.dev/blog/seth-we...

🥳 We raised some money. Expo is the best it's ever been, and this round of funding will help us get a lot better. With this money we can go faster on the things that matter: faster builds, smoother native integrations, and better e-2-e DX. Charlie wrote about what's next: expo.dev/blog/what-ex...

We should talk about Expo Orbit more. It's a free, open-source menu bar app for macOS, Windows, and Linux. Install and launch builds on simulators and devices in one click. No more dragging archives manually 😅 https://expo.dev/orbit

You don't have to migrate your React Native app to Expo all at once. This guide breaks it into four phases, each delivering value immediately. Starting is simple. It's one command: npx install-expo-modules@latest https://expo.dev/blog/how-to-incrementally-adopt-expo

For a big client Infinite Red cut their CI from 20 minutes to 6 by combining EAS Workflows, Expo Fingerprint, and EAS Update. That's 230% faster, and it makes running Maestro e2e tests on every PR practical. https://expo.dev/blog/use-expo-ship-faster

EAS Update in SDK 55 now supports bundle diffing. Devices download a small binary patch instead of the full JavaScript bundle. A typical 3MB update drops to ~0.75MB. Opt-in now, default in SDK 56. https://expo.dev/blog/ship-smaller-ota-updates-bundle-diffing-comes-to-ota-updates-in-sdk-55

MyWheels migrated a complex brownfield React Native app from RNC CLI to Expo for faster builds, easier onboarding for web developers, and better collaboration across teams. This process has only gotten easier since SDK 55...check it out: https://expo.dev/blog/from-rnc-cli-to-expo
