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.

Sometimes people ask me for my opinions about React Native tech and it's basically just this.

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.

Yo @jim.bsky.social, thanks for the excellent components + design of SRCL. Just gave my personal site a much needed refresh.

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.

Has this been the best year for React Native and Expo ever? It's definitely up there! So much to recap.

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.
