Released a massive update of my coffee timer app, Single Origin. I wanted to brew the roaster-created recipes available on the Fellow Aiden & xBloom, so I built an app that guides you through every pour, agitation, etc. Since it's built with Expo, it runs on iOS, WatchOS, Android, & Web. 👇

This is some real power. I just merged to `main` and my changes deployed to Android, iOS, and the web in ~4min total.

Congrats to us for winning best supporting actor/actress in the Bytes.dev OSScars
Best Supporting Actor/Actress: Expo. After years of supporting React Native, Expo has now teamed up with Al platforms like Replit and Bolt to allow developers (and normies) to build and ship mobile apps "without writing any code" - or at least a lot less code. Hopefully this will usher in another App Store golden age, because l've really been missing
Lightsaber Unleashed and Doodle Jump.

Free accounts get 30 builds (up to 15 iOS), free submissions, 100K hosting requests, and ~60 over the air update publishes per month on @expo.dev. And now you can automate it all so that a push to main = delivered code.

If you want to make a real mobile app, but you don’t program or know React/Expo, you can. 🔥🔥🔥 Check out @ariellecpx.bsky.social’s video: youtu.be/Q132XvlS2qg?...

Sometimes people ask me for my opinions about React Native tech and it's basically just this.
Panel 1: "Hi! My name is Jason". Panel 2, second person: "Ah! Nice to meet, you Jason". Panel 3, the person is taking that name and trying to jam it into their brain, where there are already some squares in their cartoon head. A small rectangle says "friends", a small one says "family", and a much larger one is the Expo logo. The first person's name is squished going in, clearly not sinking in. Panel 4, second person: "Say Jarvis, wanna hear about building truly universal native apps with React ath run on Android, iOS, and the web?"

We released a product called workflows, a React Native CI/CD, late last year. Heard a *ton* of feedback and there are a lot of new features. Let's dive in: 🗺️ We now display a topologically sorted map of your workflow, so you can see what's in progress, finished, failed, etc.

Since we stayed home for the holidays, I was able to get a lot of "someday list" stuff done. First up, built these shelves for my workshop. Now I have a joinery-station. Pocket hole jig, screws, bolts, glue, drills, clamps, etc.

Just turned off Apple Intelligence on all my devices and realized I was better off before. Some realizations: Apple is terrified of results that are unsavory, which means AI generated content is nearly useless. Here I tried to use the Image Playground to create images of me, angry or sad. Baha wat?

Just in time for the holidays: I updated my Scrabble word checker app. 📚 New official dictionaries (all local) 💅 Updated UI and animations 👨‍💻 SDK 52, expo-sqlite, splash screen, workflows, and more! It's free! It's open source! I hope you don't lose your turn.

LiveStore is the data layer I wish I had when working on mobile apps: Reactive, fast and fun to use! After many months of close collaboration with the folks at @expo.dev, I'm very excited to take a big step towards launching @livestore.dev.

Workflows are like a specialized tool for developers building Expo apps. They add the glue between all the steps you need to deliver your code to your users.

It was great being on the show. The people at IR are 💯. Talked about the next wave of products that are coming from Expo. In fact, we’re announcing them more fully on Wed, so this is a sneak peek. Have a listen 🎧

I could use X but: - It's lost a lot of its magic/content/people - Features are 📉 - Leadership there is ... Or I could use bsky: - Made with @expo.dev tools - People who make it are genuinely awesome - Community is magic 🌟 So, hello again my bsky friends!

How did I _just_ learn you can @ Expo docs in Cursor. We thought about adding AI to docs.expo, but its way better to be closer to the code.

What the fox? I learned that there are foxes throughout the RN docs because there used to be a family of foxes that lived by a Facebook building. Employees called them the Facebook Foxes 🦊 I hope they continue including fox bbs here and there <3

In case you were wondering, yes you can use React Compiler on Expo apps
Fun fact: React Compiler also optimized this app!
