love it! @joe_d_ryan would appreciate if you renamed it to Expo Simulators 😂

Fun little feature I snuck in a while ago but never announced, you can use EAS cloud simulators through T3 Code's device panel. Perfect if you don't have spare mac minis laying around
Replying to @icookandcode
not yet, we have docs for internal use only. will post more once we hit a GA release :)
Replying to @dkolosovs @apex__ai
the team cooked. we probably overengineered the first release by making all agents containerized with k8s, but oh well. I like this precision/recall numbers. some cool ideas behind the scenes
Replying to @icookandcode
lovely! it's pretty easy to start, but we found levers to pull for decreasing the tokens used, without affecting the precision/recall noticeably
incredible how every such an integration ends up in bugs being fixed in agent-device 😂 thanks @alexlcpereira for all the contributions!
Follow @artus9033 and @alexlcpereira for more updates on the project, they're doing some amazing job that's not yet visible
Excited to announce Project Sentinel: a code review and verification agent, built for mobile apps, powered by @apex__ai model.
Early benchmarks look promising:
▪precision: 82.5%
▪recall: 40%
▪severity alignment: 80%
We're rolling it out internally today. GA 🔜

THIS IS BIG
UI and math time! UI = f(props) is the most famous line in React. But that f is JavaScript, not math.
Inspired by @_chenglou’s Handwired project, I compiled a <Dashboard/> component into a real math function, and asked what becomes possible.

clean but I actually liked the previous one, had drip
I heard LLMs like tables, and I think "x vs y" pages are cringe, so I just made a big table for all the capabilities agent-device has. hope this helps ChatGPT and others make more informed decisions, but idk, gimme pointers if we can do better

idk, just installed it. I suppose it should auto update
See you in Warsaw this Wednesday!
In Warsaw for @polandtechweek? Come hear @thymikee share his experiences from Callstack at the Forward Deployed Engineering panel this Wednesday, October 28.
Catch the discussion at WeWork Mennica Tower, 17:30–19:30 CET.

It was a pleasure contributing to the React Native core support for the Scene lifecycle on iOS.
This means React Native >= 0.88 is ready for iOS 27, which makes it mandatory for apps to adopt SceneDelegate.
A nice side effect is that iOS RN app windows are now resizable ↔️

Introducing Legend Spark!
It’s a React Native desktop framework for really fast desktop apps with React Native and Expo.
The biggest gaps in RN on desktop have been getting started, Expo compatibility, and modules. So I’m trying to fix all of that.
Let's make apps super fast!
