The quality of your AI-generated app designs depends entirely on your prompts. A vague prompt produces generic results. A precise prompt produces designs that look like you hired an agency.
This guide teaches prompt engineering specifically for app design: the techniques, patterns, and 50+ ready-to-use templates that get exceptional results. You can apply these prompts directly in an AI UI generator to see them in action.

The Anatomy of an Effective Prompt
Every great design prompt has the same underlying structure:
[App Type] + [Target User] + [Core Features] + [Visual Style] + [Specific Screens]
Let's break down each component.
App Type
Name what you're building. Be specific about the category.
Weak: "An app for exercise" Strong: "A strength training tracking app"
Specificity helps the AI understand context. "Strength training" implies plates, sets, reps, rest timers. "Exercise" could mean anything.
Target User
Who will use this app? The more specific, the better.
Weak: "For people who work out" Strong: "For intermediate lifters who track progressive overload"
User context drives design decisions. An app for teens looks different than one for seniors, even with identical features.
Core Features
List 4-7 key features. Not everything—just what makes the app work.
Weak: "Should have all the stuff fitness apps have" Strong:
- Workout logging with set/rep tracking
- Progress charts for each lift
- Rest timer between sets
- Personal records history
Features become screens and UI elements.
Visual Style
Describe the look and feel. Reference apps. Name aesthetics.
Weak: "Should look good" Strong: "Dark theme with electric blue accents. Think Strong app meets Linear. Minimal, data-focused, no cartoons or gamification."
Visual style transforms generic UI into distinctive design.
Specific Screens
Tell the AI exactly which screens to generate.
Weak: (Not specifying anything) Strong: "Generate: home/today's workout, exercise detail with history, active workout tracking, and progress dashboard"
Explicit screen requests ensure you get what you need.
Prompt Patterns That Work
Beyond structure, certain patterns consistently produce better results.
The Comparison Pattern
Reference two apps and position between them.
Style: Like [App A] meets [App B]. The [quality] of [App A] with the [quality] of [App B].
Example:
Style: Like Notion meets Things 3. The flexibility of Notion with the visual clarity of Things 3.
This gives the AI two reference points to interpolate between.
The "Not This, But That" Pattern
Clarify by negation.
Should feel [positive], not [negative]. Avoid [thing to avoid].
Example:
Should feel premium and mature, not playful or gamified. Avoid bright colors and cartoon elements.
Stating what you don't want is sometimes clearer than stating what you do.
The User Story Pattern
Describe a moment of usage.
Imagine a [user] who [context]. They open the app to [specific action]. The interface should make [outcome] feel [emotion].
Example:
Imagine a founder at 11pm who just finished a long day. They open the app to log one quick win before bed. The interface should make capturing thoughts feel effortless and calming, not like another task.
Story creates emotional context that influences design.
The Constraints Pattern
State hard requirements explicitly.
Requirements:
- Must include [element]
- [Color/brand] constraint
- [Platform] patterns
- [Accessibility] need
Example:
Requirements:
- Must include bottom navigation (no hamburger menu)
- Brand color is #2D5BFF, use throughout
- Follow iOS Human Interface Guidelines
- All text must be readable at 16px minimum
Explicit constraints prevent unwanted results.
Advanced Techniques
Iterative Refinement Prompts
Your first prompt starts the conversation. Follow-ups refine it.
Start broad:
Create a meditation app for stressed office workers with guided sessions, mood tracking, and daily streaks.
Then narrow:
The home screen feels too busy. Simplify it to just show: current streak, today's recommended session, and a "begin" button. Move everything else to secondary screens.
Then polish:
Add subtle depth with soft shadows. The current design feels flat. Keep it minimal but add visual hierarchy through shadow and spacing.
Three rounds of iteration transforms good into excellent. For a complete walkthrough of this iterative design workflow, see our step-by-step guide to designing mobile apps with AI.
The A/B Generation Technique
Want to explore directions? Ask for alternatives.
Generate two versions of this design:
Version A: Minimal and professional, like a productivity tool
Version B: Warm and friendly, like a wellness app
Same features, different personalities.
Compare both and use what works from each.
Screen-Specific Instructions
When iterating on a single screen, be specific.
For the profile screen specifically:
- Move the settings icon from top-left to top-right
- Make the stats section more prominent
- Add a "share profile" action
- Use a gradient header like the home screen
Targeted instructions on specific screens get targeted improvements.
Platform-Specific Prompts
iOS and Android have different conventions.
For iOS:
Follow iOS Human Interface Guidelines:
- SF Pro font family
- System blue accent color (#007AFF)
- Native tab bar at bottom
- Large title navigation style
- Subtle vibrancy effects
For Android:
Follow Material Design 3 guidelines:
- Roboto font family
- Dynamic color support
- FAB for primary action
- Navigation rail on larger screens
- Material You surfaces
Specifying platform ensures native-feeling designs.

Common Prompt Mistakes
Mistake 1: Feature Soup
Bad:
Include social features, messaging, video, photos, stories, events, groups, marketplace, payments, live streaming, AR filters, and AI recommendations.
Too many features = cluttered designs. The AI can't prioritize.
Fix: 5-7 core features maximum. Add others in later iterations.
Mistake 2: Vague Style Direction
Bad:
Make it look good and modern.
"Good" means nothing. "Modern" means different things to different people.
Fix: Reference specific apps, name aesthetics, describe emotional qualities.
Mistake 3: Missing User Context
Bad:
Create a fitness app.
Fitness for whom? Beginners? Athletes? Seniors? Weight loss? Strength?
Fix: Always specify your target user in detail. If you're new to AI design, our beginner tutorial walks through the basics step by step.
Mistake 4: Platform Assumptions
Bad:
Make sure it works on mobile.
iOS and Android have different conventions. Neither is wrong, but mixing them looks amateur.
Fix: Specify platform, or generate both versions.
Mistake 5: Forgetting Screens
Bad:
[Great detailed prompt but doesn't specify screens]
You'll get whatever the AI thinks is important, which might not be what you need.
Fix: Always end with explicit screen requests.
