Mobile screens designed for the phone, not shrunk to fit.
SketchXFlow treats mobile as its own edition. Screens are composed from scratch for the phone form factor — thumb-reachable actions, real tab bars, native spacing — and every screen shares one design system, so the app holds together as you add to it.
Phone-first composition
A mobile edition is drafted for the device, not scaled down from a desktop layout that never fit in the first place.
One system, every screen
Palette, type scale, spacing and components are locked once, so screen twelve still matches screen one.
Export to native code
Take the design out as Flutter, React Native, SwiftUI or Jetpack Compose — no redraw step between design and build.
Edit by describing
Ask for a darker theme, a new onboarding screen or a different tab order. The system bounds the change so nothing drifts.
How it works
Describe the app
One or two sentences about what it does and who it is for.
Studio composes
It drafts the screens with a shared system and navigation.
Refine
Add screens, swap sections, restyle by prompt or by hand on the canvas.
Hand off
Export to Flutter, React Native, SwiftUI or Compose — or share a link.
Frequently asked
Can AI design a mobile app UI?
Yes. SketchXFlow generates real mobile screens from a text description, with a shared design system, navigation and states across the whole set — then exports them to Flutter, React Native, SwiftUI or Jetpack Compose.
Is the mobile design just the website resized?
No. Web and mobile are separate editions in SketchXFlow. A mobile design is composed for the phone from the start, with phone-appropriate layout, tap targets and navigation patterns rather than a responsive squeeze of a desktop page.
Which frameworks can I export to?
Flutter, React Native, SwiftUI and Jetpack Compose, alongside the web exports. The exported project has no SketchXFlow runtime dependency.
Do I need a designer to use it?
No. The system does the design decisions — spacing, hierarchy, colour and type — and constrains later edits to stay consistent. A designer can still take over on the canvas at any point.
How much does it cost to design an app?
You start with a one-time 150 free SketchCoins and no card. Coins meter actual AI work, so a design using stock imagery costs far less than an image-heavy one. Paid plans start at $14 per month.

Phone-first layouts, one design system across all of them, and native code when you are ready to build.
