The screen says Stars: 3, and the button’s action is stars += 1. Tap the button.

A screen is made from state: read its code, then tap a control and predict the new screen before it changes.

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

Meet the cast — the characters who teach this

  • Tabby crams the whole screen into one look — you teach her to read it row by row
  • Stackwell reads the screen top to bottom, row by row
  • Switchel flips a value on and off
  • Nametag follows a button to the one value it changes
