If typing fast in your app feels like wading through mud, you need useNativeState. Every TextField in RN has felt slightly off for years; Expo UI just shipped the fix with the new useNativeState hook. Instead of trying to keep the native input and react state in sync on each keystroke, useNativeState handles the state completely on the native side. React (JS thread) only reads the value when it needs it e.g. onSubmit, using a lightweight reference. Make your app faster, read the full blog ↓

One more tip for 2026 - React Native 0.83 ⚡️ Use instead of ternary rendering. It lets you conditionally render parts of your app without unmounting. mode="hidden" → state is preserved.

Claude Fable 5 absolutely cooked 😮 I asked it to build a habit tracker with Expo, using the Code with Beto MCP server. It shipped: – zoom transitions – sortable habit list – app icon (Code with Beto Skill) – home screen widget with a heatmap – onboarding, haptics, animations, dark mode – notification actions (mark a habit done without opening the app) 100% React Native 👇

You can now control your physical iPhone from your Mac. This is Device Hub, new in Xcode 27. They also added a new resizable window view, which tells me one thing: Apple is getting ready for a foldable iPhone 💀

Xcode 27 ships with the xcode-tools MCP server which allows your agent to interact with the simulator. This helps agents validate that the feature actually works (video is at 4x speed)

React Native hasn't shipped a new UI primitive in years. No slider. No date picker. No segmented control. So you install a community package and pray it survives your next upgrade. Expo UI kills that. Real native SwiftUI + Jetpack Compose components, written in JSX. 30-min crash course on how it actually works, some of my best teaching yet 👇

Expo Router just unlocked a new level of native on iOS 🚀 For years, cross-platform meant tradeoffs. Your app worked everywhere, but it never felt quite right. That gap is finally closing. With the latest version of Expo Router, native iOS APIs are now exposed declaratively. No UIKit wrestling. No fake UI. If you want your app to feel truly native on iOS, these are the APIs you should be using: - Native Tabs (real system tab bar) - Stack Toolbar (native header controls) - Bottom toolbars with placement=“bottom” - Bottom accessories attached to the tab bar - Zoom transitions for fluid navigation - Native sheet footers (experimental) I wrote a full breakdown with code examples and video demos of these features in my blog (link below 👇)

Since everyone is asking about Android, here's a demo using plain useState versus the useNativeState hook. TBH I don't really see a difference on Android, but on iOS useNativeState makes a huge difference. source code below 👇

I’m working on a new video about performance in Expo apps — and I’ve got to say, by far the most impressive technique I’ve found is digging into React Native Worklets (from Software Mansion). Realizing you can offload heavy computations into a custom runtime to keep your JS thread free and your app responsive just blew my mind. It feels like you can generate CPU power out of nowhere 😅 Stay tuned!

Every week another AI image app hits the top charts. The window is open, but not forever. That's why I built Platano. Today it's production ready. What's inside: - Expo SDK 56 - Agent skills for setup, rebranding, adding languages, and more - Fully native iOS and Android - Material You on Android, Liquid Glass with iOS 18 fallbacks - Onboarding flow battle-tested in my AI Tattoo app (live in the App Store) - RevenueCat payments - AI editor with Nano Banana 2 - Clean architecture your agent can extend - Interactive CLI to spin it up I use this as the base for every real app I'm building now, not just AI image apps. Ship something maintainable. Validate fast. (link below)
