TL;DR

“Make it modern and clean” is not a useful UI prompt. The strongest UI design prompts define the user’s goal, realistic content, hierarchy, interaction, platform, and screen state before visual style. Use our reusable formula and 25 paste-ready prompts to generate editable mobile screens—not polished dead ends.

Why Most UI Design Prompts Produce Attractive but Unusable Screens

“Make it modern and clean” gives AI permission to produce the most generic interface possible. The result may look polished, but missing states, fake content, weak hierarchy, and disconnected buttons make it difficult to test or ship.

We recommend specifying the user goal, screen state, content hierarchy, and primary action before describing colors or aesthetics. Visual polish should reinforce the task—not hide missing UX logic.

A glossy isolated mockup creates presentation theater. An editable screen with realistic data, predictable interactions, edge states, and a logical next step creates a foundation for a connected flow.

The prompts below use one repeatable structure with 25 targeted variations. Paste one, replace the variables, and generate a stronger first pass in seconds.

What makes an AI-generated mobile screen usable?

A usable screen has:

•One clear purpose and primary action
•Scannable information hierarchy
•Realistic labels, names, dates, prices, and errors
•Predictable platform-specific interaction
•Relevant loading, empty, error, disabled, success, and offline states
•An obvious next step in the wider flow

Pixel perfection is not the first goal. We would choose a structurally sound, editable screen over a glossy dead end every time.

A Reusable Formula for Better Mobile UI Design Prompts

A strong mobile UI design prompt should define constraints in this order:

•Product context
•User goal
•Platform
•Screen type
•Realistic content
•Required components
•Information hierarchy
•Screen state
•Interaction
•Accessibility
•Visual or design-system constraints

Decide the primary action, supporting actions, and content priority before adding stylistic references. If platform conventions matter, use our practical guides to iOS app design and Android Material patterns.

Weak prompt:

Design a modern, clean meal-planning onboarding screen.

Stronger prompt:

Design an iOS onboarding screen for a meal-planning app that helps busy adults build a weekly plan. Show step 2 of 3, selectable dietary preferences, a short benefit statement, and a Continue button disabled until one option is selected. Include selected and unselected states, visible labels, a 44-by-44-point minimum touch target, and realistic copy.

The second prompt is not stronger because it is longer. It is stronger because every constraint changes the output.

The copy-and-adapt prompt template

Design a [platform] [screen type] for [product and audience] that helps the user [goal]. Include [real content], [components], and [primary action]. Prioritize [hierarchy]. Show the [state] state and define [interaction]. Follow [accessibility and platform constraints]. Use [design-system constraints] and avoid placeholder text.

Replace only the variables that affect the screen. Do not turn one screen prompt into a complete product brief.

What to specify before visual style

Define these elements first:

•Job the screen must complete
•Real content it must display
•Information priority
•Primary and secondary actions
•Current state and recovery path
•iOS or Android behavior

Then add restrained visual direction such as “neutral palette, compact cards, one accent color, and an eight-point spacing system.” Style should shape an established structure, not substitute for one.

Prompts 1–5: Onboarding, Sign-Up, and Login Screens

These prompts include realistic labels, validation, keyboard behavior, progress, and transitions. Replace the bracketed variables to fit the product.

1. Goal-based onboarding screen

Design a [platform] three-step onboarding flow for a [meal-planning app] helping users [build a weekly plan]. Create step 2 with the heading “What do you like to eat?”, selectable Vegetarian, High-protein, Dairy-free, and No preference options, a progress indicator, concise benefit copy, and Continue. Show selected, unselected, and disabled-button states. Enable Continue after one selection.

Change the product, preference options, and benefit statement.

2. Permission onboarding screen

Design a [platform] pre-permission screen for [notifications/location]. Explain the specific value before triggering the native request. Include “Enable notifications,” “Not now,” and a later settings-recovery path. Show what feature becomes available, avoid coercive copy, and define the denied state. Use the native permission dialog only after affirmative intent.

Change the permission type and user benefit.

3. Email sign-up screen

Design a [platform] email sign-up screen with visible Name, Email, and Password labels; realistic helper text; password requirements; terms consent; inline validation; autofill; and correct email and password keyboards. Keep “Create account” disabled until valid. Show invalid email, weak password, enabled, submitting, server-error, and success states.

Change consent language and password rules.

4. Login and account recovery screen

Design a [platform] login screen with Email, Password, password visibility, “Forgot password?”, autofill, and biometric login when available. Make “Log in” primary and “Create account” secondary. Include incorrect-password, unknown-account, locked-account, offline, loading, and reset-link-sent states with actionable recovery instructions.

Change the authentication methods and lockout policy.

5. One-time code verification screen

Design a [platform] verification screen for a six-digit code sent to alex@example.com. Support automatic focus movement, full-code paste, numeric keyboard, resend countdown, and number editing. Include incorrect, expired, loading, and verified states. When expired, disable submission and offer “Send a new code.” Transition success to [next screen].

Change the destination and masked contact detail.

Prompts 6–10: Home, Search, Filters, and Detail Screens

These mobile UI prompts prioritize findability, persistent navigation, and consistent cards, spacing, typography, icons, and controls.

6. Personalized mobile home screen

Design a [platform] home screen for [product] focused on [primary task]. Include “Good morning, Maya,” recent activity, three relevant recommendations, and persistent bottom navigation. Put the primary task and latest status above the fold. Limit the screen to one primary CTA and two supporting actions. Use consistent cards and realistic content.

Change the task, recommendation data, and navigation destinations.

7. Search screen with suggestions

Design a [platform] search screen for [product]. Autofocus the search field, open the correct keyboard, and show recent searches “Standing desk” and “Monitor arm,” suggested queries, clear-text control, and Cancel behavior. Define loading after submission and keyboard dismissal on results. Avoid generic result labels.

Change the query examples and product category.

8. Search results screen

Design a [platform] results screen for “standing desk” showing 128 results, Sort, Filters with selected count, highlighted query matches, and realistic cards with names, prices, ratings, and availability. Define infinite-scroll loading. Include no-results and failed-search variants with “Clear filters,” “Check spelling,” and “Try again” recovery actions.

Change the result type, metadata, and pagination pattern.

9. Filter and sort screen

Design a [platform] [bottom sheet/full-screen modal] with grouped Category, Price, Rating, Availability, and Delivery filters. Show selected values, selected count, price controls, “Clear all,” and “Show 128 results.” Update the count as filters change. Preserve selections on dismissal and use the platform’s native modal behavior.

Change filter groups and presentation format.

10. Product or content detail screen

Design a [platform] detail screen for “Oak Standing Desk, 140 cm.” Include media, $649 price, stock status, delivery estimate, rating, specifications, returns information, sticky “Add to cart,” Save, and related products. Define skeleton loading, unavailable, saved, adding, and added states while preserving hierarchy and navigation.

Change the content type and primary action.

Prompts 11–16: Checkout, Booking, and Task Completion Screens

Real prices, dates, availability, fees, and validation expose layout weaknesses that placeholder text conceals. Each prompt requires a visible review of choices before an irreversible action.

11. Shopping cart screen

Design a [platform] cart with “Oak Standing Desk,” Walnut, 140 cm, quantity 1, $649; “Cable Tray,” Black, quantity 2, $39 each; removal, quantity editing, $727 subtotal, May 18 delivery estimate, promo code, and “Checkout.” Add empty-cart and stock-change states with clear recovery actions.

Change products, variants, prices, and delivery information.

12. Mobile checkout screen

Design a [platform] checkout with delivery address, May 18 delivery, Visa ending 4242, editable sections, and order summary: $727 subtotal, $20 shipping, $58.16 tax, $805.16 total. Make “Place order” the only primary action. Include inline validation, processing, actionable payment failure, success, and duplicate-submission prevention.

Change the amounts, address, and payment method.

13. Payment method screen

Design a [platform] payment-method screen with saved Visa ending 4242, default selection, “Add card,” card number, expiry, security code, card-brand recognition, and billing-address choice. Use native numeric keyboards and automatic formatting. Include specific accessible errors, secure-payment context, saving, declined-card, and success states.

Change the supported payment methods and billing rules.

14. Service booking screen

Design a [platform] dental booking screen for a 45-minute cleaning costing $120. Include providers Dr. Maya Chen and Dr. Luis Ortiz, available dates, time slots, local timezone, and disabled Continue until provider, date, and time are selected. Add no-availability and alternate-date suggestions.

Change the service, providers, duration, and price.

15. Booking review and confirmation screen

Design a [platform] booking review for a dental cleaning with Dr. Maya Chen on Tuesday, May 19 at 10:30 AM EDT. Include duration, $120 price, clinic address, contact details, cancellation policy, edit links, and “Confirm booking.” Add processing, success, Add to calendar, Share confirmation, and failure states.

Change appointment and policy details.

16. Multi-step form screen

Design a [platform] four-step [application] form with visible progress, one logical field group per step, preserved entries, Back and Continue, and a final review. Include visible labels, field-level validation, server errors, save and resume, loading, and unsaved-change protection. Focus the first invalid field after submission.

Change the form purpose, steps, and field requirements.

Prompts 17–21: Messaging, Profile, and Settings Screens

Related screens should reuse navigation, controls, avatars, rows, and status indicators. Privacy defaults and labels must be clear rather than persuasive.

17. Messaging inbox screen

Design a [platform] inbox with search, compose, pinned conversations, realistic names, message previews, timestamps, unread counts, and avatar fallbacks. Include Maya Chen, Jordan Lee, and Support Team conversations. Define loading, empty, offline, failed-refresh, and recovered states without changing the list structure.

Change names, message content, and inbox actions.

18. Conversation screen

Design a [platform] conversation with Jordan Lee. Group messages by date, distinguish senders, and show timestamps, delivery status, text input, attachment action, keyboard avoidance, and message retry. Include typing, sending, delivered, failed, deleted, and offline states. Preserve draft text if sending fails.

Change participant and attachment options.

19. User profile screen

Design a [platform] profile for Maya Chen, Senior Designer. Include avatar fallback, short bio, email visibility setting, Edit profile, account status, and recent product-specific activity. Prioritize information needed to understand and manage the account. Avoid decorative follower counts or statistics unrelated to the product.

Change role, account data, and activity type.

20. Edit profile screen

Design a [platform] edit-profile screen prefilled with Maya Chen, maya@example.com, Senior Designer, and a concise bio. Include image change, visible labels, inline validation, Save, saving, server-error, and saved feedback. Confirm before discarding unsaved changes. Keep users on the screen after successful saving.

Change editable fields and validation rules.

21. Settings and notification preferences screen

Design a [platform] settings screen grouping Account, Privacy, Security, Appearance, and Notifications with native controls. Include dependent settings, disabled explanations, saved feedback, sign-out, and account deletion with confirmation. Use privacy-conscious defaults and plain-language notification labels. Preserve platform-standard navigation and back behavior.

Change the groups and product-specific preferences.

Prompts 22–25: Analytics, Subscription, and Monetization Screens

Analytics and monetization screens need credible numbers, transparent billing terms, and meaningful comparisons. Decorative charts and vague plan benefits prevent informed decisions.

22. Mobile analytics overview

Design a [platform] analytics overview for May 1–31. Prioritize conversion rate 4.8%, revenue $48,320, 1,284 orders, and average order value $37.63 with comparison periods. Include one labeled trend chart and realistic recent activity. Add loading, no-data, partial-data, and refresh-error states.

Change metrics, values, and date range.

23. Analytics detail screen

Design a [platform] conversion-rate detail screen showing 4.8%, up 0.6 percentage points versus April. Include a metric definition, accessible trend chart, date filter, channel breakdown, and Export. Provide chart labels and a nonvisual text summary. Add no-data, partial-data, loading, and export-failure states.

Change the metric, comparison, and breakdown.

24. Subscription plan comparison screen

Design a [platform] subscription comparison with monthly and annual toggles. Show Basic at $9/month, Pro at $19/month, and Team at $49/month, exact limits, annual billing disclosure, current-plan status, and one clearly recommended plan without deceptive emphasis. Include Restore purchases, Terms, Privacy, loading, and billing-error states.

Change plans, prices, limits, and billing period.

25. Upgrade paywall screen

Design a [platform] paywall triggered when the user tries to export a second project. Explain the feature context, three concise benefits, $19/month price, renewal terms, and “Upgrade,” “Not now,” and “Restore purchase.” Include processing, success, payment failure, cancellation, and already-subscribed states without blocking recovery.

Change the trigger, benefits, price, and entitlement.

How to Generate Complete States and Keep Every Screen Consistent

A default screen is only one part of the interface. Request these variants whenever they affect the task:

•Default
•Loading
•Empty
•Error
•Disabled
•Success
•Offline

Create a reusable design-system block covering color tokens, type scale, spacing, corner radii, icons, buttons, fields, cards, controls, and navigation. Attach the same block to later prompts and tell the model to reference the approved first screen.

Platform constraints also need to be explicit. For iOS, define safe areas, navigation bars, sheets, native controls, keyboards, gestures, and system feedback. For Android, define Material navigation, system back behavior, bottom sheets, native controls, keyboards, insets, and snackbars.

Follow-up prompt for missing states

Create all relevant default, loading, empty, error, disabled, success, and offline variants for this approved screen. Preserve component dimensions, content hierarchy, spacing, navigation, and design tokens. Do not redesign the default state. Use specific errors that explain what happened and provide an appropriate retry, edit, settings, or alternate-action recovery path.

Follow-up prompt for cross-screen consistency

Generate the next screen using the approved navigation, grid, type scale, colors, icons, buttons, fields, cards, and interaction patterns. Preserve platform behavior and component dimensions. First provide a component inventory showing reused components. Introduce a new pattern only if no existing component can support the required task.

Accessibility constraints to append to every prompt

Ensure sufficient contrast, readable type, visible labels, logical focus order, and status cues that do not rely on color alone. Use touch targets of at least 44 by 44 points on iOS or 48 by 48 dp on Android. Support dynamic text without clipping and write specific, actionable error messages.

Accessibility also includes keyboard behavior, screen-reader labels, predictable focus movement, and clear validation—not contrast alone.

Turn One Generated Screen into a Usable Mobile Flow

Once the first screen is approved, extend it into the next logical task steps instead of generating unrelated hero screens. A commerce home screen, for example, may need search results, item details, checkout, loading, error, and success screens using the same system.

We built floow.design as a fast execution layer for this process: generate and refine connected mobile screens in seconds with one prompt. When comparing workflows, our review of AI design tools for mobile apps explains which capabilities matter beyond attractive first-pass output.

Prompt for extending a screen into a connected flow

Extend this approved [entry screen] into a connected [task] flow. Include the entry point, each primary task step, review, confirmation, recovery paths, and relevant loading, empty, error, disabled, success, and offline states. Preserve persistent navigation, design tokens, components, spacing, typography, icons, platform behavior, and data across every screen.

Four focused refinement prompts

Hierarchy

Strengthen the primary action and information hierarchy. Reduce competition from secondary elements without removing functionality or changing the established design system.

Navigation

Simplify navigation, remove duplicate destinations, and make the next step obvious. Preserve familiar [iOS/Android] back behavior and the approved navigation structure.

Copy

Replace vague labels and placeholder text with short, specific copy, realistic names, values, dates, and actionable errors. Preserve meaning and layout intent.

Clutter

Remove decorative elements that do not improve comprehension, confidence, or task completion. Keep necessary status, trust, validation, and recovery information.

Checklist: usable, not merely attractive

Before approving an AI-generated mobile flow, verify:

•Can its purpose and primary action be understood in seconds?
•Does realistic content test wrapping, density, and edge cases?
•Are loading, empty, error, disabled, success, and offline states covered?
•Are navigation, components, spacing, typography, and colors consistent?
•Does interaction follow iOS or Android conventions?
•Are labels, touch targets, errors, focus order, and text scaling accessible?
•Can a stakeholder complete and review the intended flow?
•Do recovery paths work without creating dead ends?

If the answer is no, the design is still a mockup—not a usable flow.

FAQ

What should a good UI design prompt include?

A good prompt should include product context, user goal, platform, screen type, realistic content, components, hierarchy, primary action, state, interaction, accessibility, and design-system constraints. We recommend defining structural requirements first and adding restrained visual direction only after the task and content are clear.

How long should an AI UI design prompt be?

It should be only as long as needed to define constraints that materially affect the screen. A focused paragraph often works better than a full product brief. Length does not create quality by itself; clear goals, content, states, hierarchy, interactions, and platform rules do.

How do I keep AI-generated screens visually consistent?

Approve one screen and treat it as the source of truth. Reference its navigation, grid, tokens, typography, spacing, icons, fields, buttons, cards, and interaction patterns in every later prompt. Ask for a component inventory before allowing the AI to introduce any new pattern.

Should I generate error and empty states immediately?

Yes, when those states affect layout or task completion. Error messages, empty-state recovery, disabled controls, and loading indicators can reveal structural problems hidden by the ideal default screen. Generate them while the design is still editable rather than adding them after visual decisions have hardened.

Should iOS and Android use the same UI prompt?

Not without platform-specific constraints. The product logic and content may remain consistent, but navigation, back behavior, sheets, controls, keyboards, safe areas, touch-target units, and system feedback differ. State the target platform and require its conventions in every screen-generation and refinement prompt.
