How do I turn a Figma design into a working app?

Yes, a screenshot is enough to start. AI builders read colors, fonts, layout, tables and buttons from the image and build an interface that looks like it. But a picture does not say what happens after a click or where data is stored, so you explain that in words: who uses the system, what gets recorded, and who sees what. The image gives the look; the description gives the behavior.

Yes, this is called visual editing. Instead of explaining in words which element you mean, you click it in the preview and say what to change: the text, color, size, position, or hiding it. It solves the most tiring problem with AI builders, which is the tool changing something other than what you meant. Bigger changes to business logic are still clearer as a written description.

There are three ways to make a mobile app: learn to program and build it yourself, which takes months; hire a freelancer or a company and pay for their time; or use an AI builder that creates the app from your description. Whichever you choose, start with a small version that solves one problem, test it on real phones, then prepare it for the Apple and Google stores.

A requirements document answers five questions: what is the problem and for whom? Who uses the system and what is each role? What can each user do, written as short stories? How do we know each feature is done, meaning the acceptance criteria? And what will we not build now? Write it in plain language in a few pages. A short, clear document beats a long one nobody reads.
