AI App UI Design Generator
iOS and Android screens, composed at real device proportions.
App screens live or die on spacing. This AI UI design generator 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. High-fidelity mockups, exported as images with no watermark.

Generated from a one-line prompt — no template picked.

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.
App screen sizes and safe areas
A phone canvas is unforgiving — room for one primary action, a short list and very little else. These are the numbers a screen has to live inside:
- iPhone — 390 × 844 pt
- The workhorse frame for recent Pro-sized devices. Design here and larger phones simply get more breathing room.
- iPhone Pro Max — 430 × 932 pt
- Worth checking if your layout depends on a fixed number of list rows being visible without scrolling.
- Android — 412 × 915 dp
- The common Pixel-class frame. Close enough to iPhone that one structure serves both, with different chrome.
- Bottom safe area — 34 pt
- The home indicator sits here. Any button flush to the bottom edge is a button partly under a system gesture.
- Tap targets — 44 pt iOS, 48 dp Android
- The minimum either platform considers reliably tappable. Smaller controls look tidy in a mockup and fail in a hand.
Generating directly into the device frame keeps that constraint in front of you. Elements compete for real space, so the design has to decide what matters instead of deferring it to whoever builds it.
What actually differs between iOS and Android
Naming the platform in the prompt shifts real details, so an iOS screen does not arrive wearing Android chrome. The differences users notice:
- Navigation title
- iOS uses a large title that collapses as you scroll. Android uses a top app bar with the title left-aligned at a fixed size.
- Going back
- iOS shows a back chevron with a label at the top left. Android relies on the system back gesture, so the screen does not draw its own.
- Tab bar vs bottom navigation
- Visually similar, behaviourally different — iOS tab bars sit at 49 pt with labels always shown; Material bottom navigation is taller and handles active state differently.
- The floating action button
- A Material pattern with no iOS equivalent. An FAB on an iOS screen is the fastest way to make a mockup look wrong to an iOS developer.
- Sheets
- iOS sheets use detents and a grabber; Android bottom sheets behave and are styled differently. Both are worth naming explicitly.
- Type
- SF Pro against Roboto, with different default scales. It changes how much copy fits on a row more than people expect.
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
Name the app type and the specific screen — home, browse, checkout, settings — then list the two or three components that must appear. Name the platform too, so the chrome is right. The screen comes back at device size, and you refine it in chat before exporting or asking for the next screen in the flow.
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.
No — there is no Figma export, and designs come out as images rather than layers. If your workflow ends in Figma, the practical route is to use this to settle the layout and visual direction fast, then rebuild the agreed screen with your own components. That is usually quicker than editing someone else’s generated layer tree anyway.
No. This produces the design, not the implementation. Developers use the exported screens as the visual reference — exporting at 2× or 3× keeps spacing, type sizes and component detail legible enough to build from.
No. Nothing is stamped on your export, including on the free plan, so screens can go straight into a pitch deck, a case study or an app store listing mockup.
Yes, with credits included and no card needed. Generations cost 2 credits; refinements and exports are free.
