Creating professional mobile app designs used to require weeks of work in complex design tools—or hiring expensive designers. Not anymore. With AI mobile design generators like Komposo, you can create stunning iOS and Android app interfaces in minutes, not days.

In this complete guide, you'll learn exactly how to use Komposo's AI mobile design generator to create beautiful mobile app designs. We'll cover everything from getting started to advanced prompt techniques, with real examples you can use right away.

What Is an AI Mobile Design Generator?

An AI mobile design generator transforms text descriptions or images into complete mobile app interface designs. Instead of manually placing every button, card, and navigation element, you describe what you want—and the AI creates it for you.

Komposo's mobile generator is specifically optimized for mobile-first design. It generates designs at iPhone 14 dimensions (390px × 844px) with proper mobile UI patterns like bottom tab navigation, status bars, safe areas, and thumb-friendly touch targets built in.

The key difference from general AI tools: mobile-specific generation understands the unique constraints and patterns of mobile interfaces. Your designs come out looking like real apps, not shrunk-down websites.

Why Use AI for Mobile App Design?

Before diving into the how, let's be clear about why this matters:

Speed

Traditional mobile design workflow: sketch ideas → create wireframes → design mockups → iterate based on feedback → export assets. This takes days or weeks. With AI, you go from idea to polished mockup in under a minute.

No Design Skills Required

You don't need to master Figma, understand color theory, or know what a "safe area" is. The AI handles the design fundamentals while you focus on what matters—your app's concept and user experience.

Faster Iteration

Testing multiple concepts is expensive with traditional design. With AI, you can generate 10 different approaches to your home screen in the time it would take to manually create one. This lets you explore more ideas and find the best solution faster.

Production-Ready Code

Unlike static mockups, Komposo exports clean HTML/CSS code that you can use as a starting point for development. This bridges the gap between design and development.

Getting Started: Your First Mobile Design

Let's walk through creating your first mobile app design step by step.

Step 1: Open the Builder

Navigate to Komposo's builder and create a new project, or open an existing one. You'll see the canvas with an input area where you can start generating.

The four available modes are:

  • Mobile App: 390px width for iOS/Android screens
  • Web App: 1440px width for dashboards and applications
  • Marketing Website: 1440px width for landing pages
  • Component: 900px width for individual UI components

Make sure Mobile App is selected before generating.

Step 3: Write Your Prompt

This is where the magic happens. Describe the mobile screen you want to create. Here's a simple example:

PromptDesign a fitness tracking app home screen with today's workout summary, step count progress ring, calorie counter, and quick action buttons to start a new workout. Use a dark theme with electric blue accents.

Click Generate and watch as the AI creates your mobile design in real-time, streaming the result into the canvas.

Step 4: Refine and Iterate

Your first generation is a starting point. Use the edit feature to refine specific elements:

PromptMake the progress ring larger and add a weekly activity graph below it.

Each edit builds on your existing design, letting you fine-tune until it's exactly right.

Mobile Prompt Templates That Work

The quality of your AI-generated design depends heavily on your prompt. Here are proven templates for common mobile screens:

Home Screen / Dashboard

PromptDesign a [app type] home screen with [primary content], [secondary content], and [navigation pattern]. Include a [header style] at the top and [action buttons]. Use [theme] colors with [accent color] highlights.

Example:

PromptDesign a banking app home screen with account balance card prominently displayed, recent transactions list, and quick transfer buttons. Include a clean header with notification icon and bottom tab navigation. Use a light theme with deep blue accents.

Onboarding Flow

PromptCreate a mobile onboarding screen for [app type] that shows [value proposition]. Include [illustration style], a headline, supporting text, and a prominent 'Continue' button with skip option. Use [color scheme] colors.

Example:

PromptCreate a mobile onboarding screen for a meditation app that shows the breathing exercise feature. Include a calming illustration with soft gradients, a welcoming headline, short benefit text, and a prominent 'Get Started' button. Use calming blue and purple tones.

Profile / Settings Screen

PromptDesign a profile screen for [app type] with user avatar, name display, and organized settings sections for [section 1], [section 2], and [section 3]. Include [specific controls like toggles or dropdowns].

Example:

PromptDesign a profile screen for a social fitness app with user avatar, name and stats display, and organized settings sections for account, notifications, and privacy. Include toggle switches for key settings and a sign-out option at the bottom.

List / Feed Screen

PromptDesign a [content type] list screen with [card/row style], showing [key information per item]. Include search bar at top, filter options, and [empty state consideration]. Use [visual style].

Example:

PromptDesign a recipe list screen with card-style entries showing food image, recipe name, cooking time, and difficulty badge. Include search bar at top with category filter pills. Use warm, appetizing colors with generous spacing.

Detail / Content Screen

PromptDesign a detail screen for [item type] with [hero element], key information section showing [details], action buttons for [primary action] and [secondary action], and related content below.

Example:

PromptDesign a product detail screen for a sneaker shopping app with large product image gallery, price and size selector, 'Add to Cart' and 'Save' buttons, product description section, and customer reviews below.

Advanced Techniques for Better Results

Use Reference Images

Komposo can analyze uploaded images to understand the style and structure you want. This is incredibly powerful for:

  • Competitor analysis: Upload a screenshot of an app you admire, then describe what you want differently
  • Converting sketches: Upload hand-drawn wireframes and let AI transform them into polished designs
  • Style matching: Upload brand assets to guide the AI's color and typography choices

To use this, click the image upload button in the input area and attach your reference before writing your prompt.

Generate Multiple Screens at Once

For complete app flows, use Multi Screen mode. Instead of generating one screen at a time, describe your entire app:

PromptDesign a habit tracking app with screens for: daily habits checklist, habit creation form, weekly progress dashboard, and settings page. Include consistent navigation and a motivating color scheme.

The AI will extract individual screens, suggest a coherent theme, and let you review before generating all screens in parallel.

Use Section References

When you have an existing screen you like, you can reference it when creating new screens. Use the @ mention feature to reference existing nodes:

PromptCreate a notification settings screen that matches the style of @HomeScreen, with toggle switches for each notification type.

This ensures design consistency across your app.

Apply Themes for Consistency

Komposo's theme system lets you define colors, typography, and spacing once, then apply them to all your screens. Access themes from the palette icon in the generation interface.

Available public themes include:

  • OpenAI: Clean, minimal light theme
  • Claude: Warm, approachable aesthetic
  • Brutalism: Bold, raw design language
  • Material: Google's Material Design patterns
  • Airbnb: Friendly, modern style
  • Twitter/X: Dark mode optimized

You can also create custom themes or extract themes from existing screens to maintain brand consistency.

Mobile Design Best Practices

Even with AI, understanding mobile design principles helps you write better prompts and evaluate results:

Thumb-Friendly Navigation

Most users hold their phone with one hand. The AI automatically places important actions within the natural thumb zone, but you can reinforce this:

PromptPlace the primary action button at the bottom of the screen within easy thumb reach.

Touch Target Sizes

The AI generates buttons with minimum 44×44px touch targets by default. For critical actions, request larger targets:

PromptMake the 'Add to Cart' button extra large and prominent for easy tapping.

Bottom Tab Navigation

The most common mobile navigation pattern. The AI generates proper tab bars with:

  • 4-5 items maximum
  • Icons with labels
  • Active state indication
  • Proper safe area padding for notched phones

Visual Hierarchy

Guide users' eyes to what matters most:

PromptMake the account balance the most prominent element, with secondary stats below and action buttons at the bottom.

Whitespace and Breathing Room

Mobile screens are small. Generous padding prevents the cramped feeling:

PromptUse comfortable spacing between elements. Don't crowd the interface.

Tips for Better Mobile Prompts

Based on analyzing thousands of successful generations, here's what separates good prompts from great ones:

Be Specific About Content Type

Instead of: "Show some statistics" Try: "Display step count as a circular progress ring, calories burned as a card, and active minutes as a horizontal bar"

Specify Visual Hierarchy

Instead of: "Include user info" Try: "Show user avatar prominently at top, name below it, and stats in a horizontal row underneath"

Name the Navigation Pattern

Instead of: "Add navigation" Try: "Use bottom tab navigation with Home, Search, Create, and Profile tabs"

Reference Real Apps

Instead of: "Make it look modern" Try: "Style similar to Spotify's dark theme with vibrant accent colors on key actions"

Include Functional Details

Instead of: "Add buttons" Try: "Include a floating action button in bottom right for creating new entries, and secondary action icons in the header"

Frequently Asked Questions

How does the AI mobile design generator work?

Komposo uses advanced AI models to interpret your text descriptions and generate HTML/Tailwind CSS code that renders as a visual mobile interface. The mobile mode specifically applies mobile-first design principles, proper dimensions (390px width), and native UI patterns like bottom navigation, status bars, and safe areas.
