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

I wasn’t going to work on my coffee timer app until I saw the output of @expo Agent. It helped me create the *very slick* timer animation.
🙌 We've begun to invite more people from the Expo Agent waitlist into the beta.

These queue times are going to fluctuate as demand changes, but happy this week is looking better. You can see demand on our queue dashboard: expo.dev/eas-build-status

Here's an @expo workflow that's really nice: make an iOS build, send to TestFlight, and share it with every testing group. It even sends a changelog for Apple's TestFlight review.
Just 17 lines to automate this whole flow. The complete YAML config below 👇

We add a TestFlight job to Workflows. Now you can send to TestFlight internal and *external* groups automatically, with < 10 lines of YAML.

The precompiled React Native on iOS feels so good, especially when paired with the `type: testflight` job. Getting my project to the app store was so quick.

I’m working on slides for Expo’s keynote at App.js next week. How many times should I include @kentcdodds in the keynote? 😂😇

This is so important. At @expo we say, “write once, native everywhere”. Your app should feel right for every user.
