AI App UI Design Generator
iOS and Android screens, composed at real device proportions.
App screens live or die on spacing. Design Maker AI composes into a real device frame — 9:19.5, safe areas respected, tab bar where a thumb can reach it — so what you get is a screen you could hand to a developer, not an illustration of an app.

Why use this instead of a template
Device-accurate frames
Composed at 390 × 844 with status bar and safe areas accounted for, so nothing important hides under a notch or a home indicator.
Screen flows, not one-offs
Ask for the next screen in the flow and the navigation pattern, spacing and component style carry through.
Light and dark variants
Request the dark counterpart and the palette is remapped properly rather than inverted.
Direct the details
Bigger balance card, chips above the list, a filter sheet — each request edits the screen you already have.
How the app ui design generator works
Four steps, and only the first one costs credits.
- 1
Name the screen
The app type and the specific screen: home, browse, checkout, settings.
- 2
List the key elements
The two or three components that must appear — a balance card, a chart, result rows.
- 3
Generate at device size
The screen comes back framed at phone proportions with real component structure.
- 4
Extend the flow
Ask for the next screen and keep the system consistent across the set.

Who it's for
The jobs people bring to this tool most often.
Product teams
A concrete screen to react to in a kickoff instead of a whiteboard sketch.
Founders
Investor-ready app visuals before an engineer is hired.
Developers
A design reference when there is no designer on the project.
Portfolio work
Case-study screens that look production-grade.
App store assets
Screenshot frames for a listing.
Client pitches
Three interface directions in the time one used to take.
Designing for a phone-shaped canvas
A 390 × 844 point canvas is unforgiving. There is room for one primary action, a short list, and very little else — which is why app screens that were designed on a desktop artboard usually feel cramped once they reach a device.
Generating directly into the device frame keeps that constraint in front of you. Elements compete for real space, so the design has to make a decision about what matters instead of deferring it.
iOS and Android conventions
The platforms differ in ways users notice: navigation titles and back affordances, tab bars versus bottom navigation, sheet behaviour, and default type scales. Naming the platform in the prompt shifts those details, so an iOS screen does not arrive with Android chrome.
When a design has to serve both, generate the iOS screen first and ask for the Android counterpart — the structure holds while the platform-specific components are swapped.
From one screen to a flow
Single screens are easy; consistency across eight of them is the actual work. Because each refinement edits an existing design, a flow can be built by asking for the next step and stating what changes — "same navigation and spacing, now the confirmation screen".
That keeps the component vocabulary stable, which is what makes a set of screens read as one product rather than six unrelated mockups.
App UI Design Generator FAQ
They are composed at 390 × 844 points (9:19.5), a standard modern phone frame, with status bar and safe areas accounted for.
Yes. Name the platform in the prompt and the navigation patterns, components and type scale follow that platform’s conventions.
Yes. Generate the first screen, then ask for the next step in the flow — the navigation pattern, spacing and component style carry across.
You get high-fidelity screen designs you can refine in chat and export as images. Use them as the visual reference for a build or a design file.
Yes, with credits included and no card needed. Generations cost 2 credits; refinements and exports are free.
