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.

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.

AI agents are shipping more PRs, but verifying mobile UI still needs a real device.
New on the blog today: build a QA agent with EAS Workflows and agent-device that checks your app on iOS and Android for every PR.

Small teams can't afford to chase broken dependencies.
Fig (5 engineers, millions of users with food allergies) shares how they incrementally replaced community packages with Expo SDK modules after getting burned one too many times: expo.dev/blog/how-fig...
🙌 It's almost impossible to find a (non Expo) youtube tutorial covering Expo's Services. Until now.
There is a massive new React Native crash course from the talented team at JS Mastery that covers SDK 55 and Expo's Services.

💡 B2B mobile apps face a different adoption challenge than consumer apps. You're competing for budget approval and security reviews, not App Store attention.
What actually works: fast onboarding, case studies, pilot programs, and long-tail keywords.

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

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.

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...
