01 — the loop
A real session, replayed
The first thing ever built with Slapp — told to the phone, built by the agent, verified on its own screenshot.

02 — living cells
What it does
Floating bubble
Glass overlay. Live transcript. Stop anytime.
Live canvas
The app on screen while it is built.
Apple Watch
The same loop, for the wrist.
Annotate
Circle it. The agent sees your marks.
One tap, one project
Folder, repo, session — automatic.
Real Pi sessions
An actual coding agent. Not a toy.
Share cards
Every app gets a page to send anywhere.
Self-healing
Bonjour, keepalive, restarts. It just runs.
03 — how it works

Talk.
Hold the mic, say what you want. Feed it photos, files, scribbles.
It builds.
Xcodegen, Xcode, the simulator — a real toolchain doing real work.
You watch.
The canvas streams the app as it takes shape. Chip in whenever.
04 — install
One line
$
curl -fsSL https://slapp.dev/install.sh | bash
