Expo SDK 55 introduces the isolated brownfield approach: package your Expo app as a precompiled native dependency and embed it in your existing app.
Swift & Kotlin devs never touch Node.js. React devs get a clear surface to contribute. Complexity stays contained.

You can now build iOS home screen widgets and Live Activities as React components in Expo.
No Xcode target setup. Define your widget with @expo/ui & CNG handles the rest.
◆ Interactive home screen widgets
◆ Live Activities for Lock Screen and Dynamic Island

Illustration of three differently colored mobile app icons labeled Dev, Preview, and Production, symbolizing build variants or app flavors for separate development and release environments.
Shipping the “same” app in dev, preview, and production without release chaos?
We’re using App Flavors with Expo + EAS to keep builds cleanly separated.

Curious how others structure their builds.
🍁 Calling all Maple Mobile Devs - we're hosting our first ever meetup in Toronto and we'd love to see everyone from that community in person.
The event is this Thursday, March 5th. Details are here:

Expo Router v55 is here.
♢ Native navigation UI, built like React (Stack API, toolbars, native tabs)
♢ Dynamic platform colors, zoom transitions
♢ Better iPad support with split view
♢ Stronger web story with expo-server, headers, experimental SSR + loaders
Blog + demos: expo.dev/blog/expo-ro...
This is a hard problem to solve. Sounds like you’re doin a great job.
You all should have seen @buildwithtori.com's demo at the Seattle meetup this week. Pretty much: 🤯
Hope to see all the local Seattle devs at the next one: partiful.com/e/096o98XaHX...
Less is more: Bundle diffing comes to EAS Update.
Instead of downloading the full bundle on every update, devices now receive a binary patch of only what changed.
Result: ~75% smaller downloads.
♦ A 3MB update drops to ~0.75MB
♦ Opt-in beta, safe fallback to full bundles

Expo SDK 55 is out 😅
RN 0.83, React 19.2 & a long list of things that make your app faster, smaller, & easier to build
♦ Hermes bytecode diffing cuts update sizes by ~75%
♦ Brownfield support gets a serious upgrade
♦ MCP now queries EAS + TestFlight crashes

Nice new tutorial about how to properly combine Claude Code with Expo to vibe code a mobile app: www.youtube.com/watch?v=Z4Dj...
Onespot manages 200+ individually branded school apps from a single Expo codebase.
Deploying to all of them used to take 7-10 hours. Now it's one button tap from an iPhone.Here's how they wired it up:

If I had to learn React Native from scratch in 2026…
I would do it very differently.
AI changed the game.
Courses aren’t enough.
And most people are still learning the wrong way.
Did you know! You can append .md to any @expo.dev blog or changelog post to get the content as markdown
Psst! this will also work with accept headers
Join us in Brooklyn if you can next week. Going to talk 🦞 and MCP, and whatever @yef.im has in his heart.
📸 Just published a blog post about building AI-first photo apps with Expo and CoreViz SDK.
Auto-generate descriptions, semantic search across your library, edit images with text prompts. All client-side or via API.
Really impressive, beautiful project from Wassim Gharbi:

Expo MCP Server now supports Build & Workflow management.
You can ask your AI assistant to check build status, view logs, trigger workflows, and debug failures without leaving your editor.
♦ Full pipeline control through conversation
♦ Claude Code, Cursor, VS Code support

Our web dev team went deep with Claude or the last month. In the process, we learned a few things. @juwan.dev shared insights with the company yesterday at All Hands and then wrote up a blog to share our learnings with you.
What works? What doesn't? It's all in here:

Expo StatusBar is a crucial library for Expo devs. It provides the same interface as the React Native StatusBar API, but with slightly different defaults to work great in Expo environments.
Great video here from Kadi Kraman about how to get the most out of it.

The best B2C apps grow through sharing. But sharing doesn't happen by accident.
You have to build the mechanism and the motivation. There are examples and best practices in our blog post today.

🔴 Great livestream from Sonny Sangha for anyone who wants to see SDK 55 in action.
He builds an AI Dating Mobile App from scratch on stream using all the bells & whistles you'd hope to see - Liquid Glass, smooth haptics, file based routing, reanimated. Check it out: www.youtube.com/live/y-Vvj95...
💡 Tons us useful advice for indie devs in today's guest blog post. Here are a couple pearls of wisdom that stood out:
⬩ Start with Expo's Services on day one.
⬩ Write tests: skipping them caused regressions later
⬩ Polish matters: haptics took ~1 hour
