Lesson 2 / 126 min read

Build your first app

From a blank screen to live: your first build step by step, and what to watch for.

1
Write what you want
In the box on the home screen, describe your business: who uses it and what they do. e.g. "An appointment book for my salon where customers can book by phone number."
2
Answer the questions
Smart Build asks up to 3 questions if needed. They sharpen the scope — answering them noticeably improves the result.
3
Review the plan
You get a title, scope, screens and data model. You also pick the output language, accent color and model here. Nothing is built until you approve.
4
Watch it build
The app builds in the background — you can close the page. It arrives full of realistic sample data and ready to use.
5
Try it and refine
Actually use it in the preview. Say what you want changed in a sentence: "add a search box", "drop the price column".
6
Publish
Hit Publish and the app goes live at its own address. Later edits don't touch the live version until you republish.

Your description

“An appointment book for my salon where customers book with their phone number”

An animation — it starts no real build and spends no credit.

Try it yourself

Build a small app you can genuinely use, and publish it.

What you should end up with

You end up with an app that opens on your phone, stores data and can be shared — and you have seen the change loop first-hand.

Yes. Every generation is kept as a version; restore any earlier state with one click from version history. Your data is independent of versions — rolling back never deletes records.
Yes. A build belongs to your account, not a device; your draft, answers and choices live on the server.
Yes — the "Discuss" button in the composer. While it's on your app is NOT touched: no code change, no new version. If the conversation lands on a concrete change you get a ready build instruction, one tap into the composer.
