Took inspiration from Solarin Johnson and built a Nintendo 64–style rumble effect for the disabled state of our pressables in our upcoming @expo.dev fantasy football app, @sundayff.app . It has heavy haptic feedback, of course!

I had planned about a day to get a decent drag and drop list working for reordering users' draft queues. I saw react-native-sortables on Reddit and decided to give it a try—
had it working flawlessly in like 45 minutes. Absolute joy to use. Awesome lib, thanks @matipl01.bsky.social !

I'm convinced that after a few rounds of user feedback and polishing, Liquid Glass will be a worthy upgrade to Apple's design system.
Last week, I had an exchange with @codewithbeto.dev
about how nice the iOS 26 context menu looked compared to some other Liquid Glass components.

Our consulting team helped @rainbow.me cut iOS E2E test times by 50% and shipped a fix to React Native core. Read how below
Sped up iOS e2e test runs with Maestro by ~4x in the Rainbow app 🔥
The improvement was actually in React Native core. Here’s what was happening, and how it was fixed 🧵

After watching the #WWDC25 sessions on Liquid Glass and the new design system, I'm pretty excited! A lot of attention went into the material, and I'm looking forward to experimenting with it.
I'm making a TLDW doc for the team, which I'll share here too😁

Overall, I'm very excited for "Liquid Glass" and to watch how it evolves. I love how vibrant it is—it allows for more colourful designs without being too much.
In some examples, I think the refraction is a little too high and the blur a little too low but those are minor details that can be tweaked

I've been spending time polishing or *adding delight* to @sundayff.app (wip). Every year it gets easier and easier, thanks to @expo.dev and @swmansion.com reanimated. Here's a fun progress bar we did for the onboarding.

Keyboards and ScrollViews are a pain! MagicScroll can help :D
We just updated Magic Scroll and it is now compatible with the new architecture and @expo.dev 52!
The easiest way to manage keyboards and ScrollViews on long forms - give it a try.

We made it so that it felt as close to the iOS behaviour as possible - we had to find a solution for deep press which doesn't exist on Android, and I think it is pretty seamless!

React Native being 'good enough' for a V1 is the same kind of misconception people had saying Expo was only good for prototypes... All depends on the skill level of the team building it.
Asked this question two years ago.
The answer now (based on talking with recruiters) seems to be a definite "yes, there is a decline. Early-stage startups overwhelmingly choose cross-platform mobile. Specifically, VC-funded ones in the US bias strongly to React Native"
