Paper App Prototype
Draw a 4-screen app on paper, test it with real people, then ask an AI to review it and compare what it caught.
Materials You'll Need
- This printable sheet (with 4 screen frames)
- Pencil
- Scissors (optional, to cut the screens apart)
- 2 people to test it
- A grown-up's Claude or ChatGPT account, used together

How It Works
- 1
Pick a tiny app that helps one person do one thing (examples: 'Pick tonight's board game,' 'Remember to water the plant').
- 2
Draw 4 screens in the frames: a start screen, two middle steps, and a 'done' screen. Draw every button.
- 3
Test with 2 people. Show screen 1 and say 'Tap where you'd tap.' Swap to the screen that button leads to. Don't explain. Write their moves in the tester notes.
- 4
With a grown-up, describe your screens to an AI and ask: 'What would confuse someone using this app for the first time?' Write down what it says.
- 5
Compare: What did the people catch that the AI missed? What did the AI catch that the people missed? Redraw one screen.
Your Work
Draw your screens. Fill in the tester notes and the AI's review. Write what you'd fix first.

What the AI reviewer said
People caught / AI caught / I'll fix first
Parent Notes
Real designers test paper screens before writing any code, because changing a drawing is cheaper than changing an app. Keep testers from getting help: the silence is the data. The AI can only review what your child describes, so it often misses what a real person trips on. Ask: 'Who was the better reviewer, and why?'
