🥳 We raised some money. Expo is the best it's ever been, and this round of funding will help us get a lot better. With this money we can go faster on the things that matter: faster builds, smoother native integrations, and better e-2-e DX. Charlie wrote about what's next:

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. 👇

lately I can't imagine working without git worktrees but there are a couple of things I don't care about, path of the tree, name of the tree, always start from origin main. so over the weekend I (Claude) created a simple SwiftUI app for a quick creation of the trees

`If this is intentional, prepend VarName with an underscore.` This is a dangerous recommendation these days, I've noticed agents tend to add _ without intention instead of removing the dead code.

Although I barely write code now, I still run commit and push handful of times, since 15+ tool calls to do it by an agent seems like a waste to me.
