We can build apps faster than ever. The bottleneck now is the last mile: getting through app review. I put together a cheat sheet of how long it actually takes to publish to the App Store and Google Play based on what I've seen. Does it match your experience?

Get started with Observe today everybody! We'd love to hear what you think 🚀

Expo@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...

Need native functionality not covered by the Expo SDK? Learn how to write your own native modules with Expo in this excellent tutorial blog from @entiendonull.bsky.social. He walks through a real world example for detecting audio routes with Swift and Kotlin. expo.dev/blog/how-to-...

”Quality is a function of iteration”, that is such a great quote! If you missed Evan's talk at React Conf, check it out now. Lot's of good stuff in there and another epic live demo 🚀

🤯 End to end iteration from the palm of your hand. In his lightning talk from React Conf, Evan Bacon demonstrates the limitless potential for building mobile apps when you have the tools to coninuously iterate on your apps. https://www.youtube.com/live/p9OcztRyDl0?si=EDqdt8-4BI-_DvfD&t=21364

The iOS queue times for Free plan users on @expo.dev were around 4 hours at this time last week. We increased our Mac capacity today. We're seeing <10 min queue times right now. ⚡ Subscribers are seeing 0 min queue times.

The new 𝝠 Expo home page is live: expo.dev We were overdue for a new home that tells the story of what Expo has become: Everything you need to build apps. We added more pages to explain how Expo serves different stages of business growth across different industries. We'll 🧵 some of those below ↓

I'm so excited about this 🤩 Recommend checking out the blog post, such a good read!

Would your CTO hold the 🎤 for you? Great scene last night at our Seattle meetup - hosted by @jim.bsky.social & the @internetstudio.bsky.social team. @pfrazee.com, CTO of @bsky.app, holding the mic for @hailey.at to demo authentication with ATproto in Expo apps. Thanks to everyone who came out!

🤗 Next to Pike Place market tomorrow @hailey.at will demo authing and interfacing with Atproto in expo apps in under 20 mins. And @reedharmeyer.bsky.social will show wild stuff @skylight.social does with Expo Router. There will be food and bev as well. Come hang! app.getriver.io/beta/events/...

Had some spare time this morning and took @expo.dev SDK54's new native tabs in expo-router for a spin. The API feels great. Native tabs are a big piece of the puzzle- and now with native, JS, and custom tabs, it’s easier than ever to match any app’s design language 🚀

EAS Update is more than a way to fix bugs fast. It’s a deployment superpower if you know how to use it. Here are a couple examples from the blog: ◆ Safe Continuous Deployment ◆ Simplifying an already-frequent release schedule ◆ For more frequent releases ◆ Hot-fixes only expo.dev/blog/eas-upd...

You might be sleeping on some of the most powerful features in the Expo SDK. 🛠️ Remote build cache 🎙️ Expo Speech 💾 SQLite async storage 🧭 Router UI 🔄 Background tasks 🧠 API routes (yes, full stack in Expo) Check out the post (with video) from @codewithbeto.dev: expo.dev/blog/5-expo-...

React Native is getting faster—and greener—with precompiled packages. 🔧 One build per release instead of one per dev ⚡ RNTester clean builds: 120s → 10s (M4 machines) 🌿 Lower power usage, better battery life 🧩 Easier to add to large brownfield apps More info: expo.dev/blog/precomp...

Just spent a month in Ecuador after 8 years away - had to use my saved vacation days before heading into new, exciting endeavors soon, so I took the chance to visit family, friends, and a bunch of my favorite spots. I lived there for years and, it still feels like home ❤️🇪🇨 Here's some highlights 🧵

Caught up with these guys (great devs and former colleagues) in Quito, Ecuador the other day. Besides catching up and having traditional Ecuadorian ceviche for lunch we also chatted about #ReactNative and played around with a universal @expo.dev app 🚀 Great day! 🇪🇨😎

The fact that you can stay in the comfort of @expo.dev and still write a custom native module when you need to? That's freedom. This is a great Beto-vid about Expo Modules - check it out 🚀

📢 Here’s my video on how to build a custom Expo module! I had such a great time using the Expo Modules API — bringing native capabilities to your app has never been easier! We tap into Apple’s new Foundation Models framework to bring on-device LLMs to your Expo app. 🎥 youtu.be/zReFsPgUdMs
