Every health app I’ve tried shows water as a number going up. I never felt anything looking at it.
So I wondered: what if the water was actually there? Every glass you add pours in for real, splashes, settles, and bubbles rise to the top. It’s a simulation running on the phone, not a video.
How I built it 👇
1 → designed the screens in Figma
2 → Claude built them natively in SwiftUI through the Figma MCP
3 → Liquid Glass for the bars, the charts straight from my Figma vectors
4 → a Metal shader for the water, so every glass actually pours in
There’s never one magic prompt for something built from scratch. It’s ideas, design, testing and a lot of small fixes. What makes it fast now is knowing exactly what you want.
