ScreenForge

Real apps are screens made from state. Read a little screen’s code — a Text, a Toggle, an if, a Button — see the screen it makes, then tap a control and predict the new screen. A tap runs an action that changes the state; the screen is just the view re-reading it.

Every screen here is drawn by really running the view — nothing is a stock picture. Runs on your device; nothing leaves it.
