I hit a React Native performance wall building a workout feed.

Each card needed a route preview, so my first pass was simple:

Embed a MapView in every row and let FlashList handle the scrolling.

Reasonable idea.

Didn’t scale.

Fable 5: our most capable model yet*

*not capable of rendering HTML 😭

First sale today.

It’s not about the amount. It’s the feeling that someone I’ve never met found enough value in something I built to pay for it.

Started as an idea, turned into late nights, bugs, iterations, and a lot of second-guessing.

Small milestone. Back to building 🚀

@tdinh_me Thanks! 😄 Had to add the confetti for the little dopamine hit haha.

If you’re into running, you can give it a try:

Lived long enough to see a MacBook become the value option.
Better build. More RAM. Bigger SSD. Faster chip. Lower price.

We really are in the weird timeline.

Been using Apple Watch for running for a while, but I always found it annoying to quickly see my PR progress across different distances.

I wanted something simple:
• yearly PRs vs all-time PRs
• compare progress between years
• see achievements at a glance

So I ended up building my own app: PR Atlas 🏃

Works best with Apple Watch, but any running app that syncs with Apple Health is supported too.

Back from a long hibernation

Apple finally let me into the Developer Program, which means I can now officially pay $99/year to create bugs for iPhone users.

Time to be back.

@ConnCFC My man disappeared.

[William Tran @dangiscoding]

@michalmalewicz 100%, be your own first customer.

If you use it daily, you’re building something real.

At this point Siri isn’t an assistant
she’s a group chat admin forwarding your question to smarter people
