UI Copy Generator - iOS, Android & Web Microcopy

Overview

Generate complete interface microcopy for iOS apps, Android applications, React web dashboards, and Electron desktop software in under 2 minutes. This template produces headlines, button labels, form fields, error messages, empty states, tooltips, and VoiceOver-compatible screen reader text that match your product’s tone while meeting WCAG AA accessibility standards.

Used by product designers shipping SaaS features before Friday deployments, UX writers documenting fintech apps during two-week sprints, and design teams maintaining consistent voice across mobile and web without manual copywriting for each platform.

Use Cases

• Write Swift iOS login screen copy for a fintech app passing App Store review next Monday
• Generate React Native error messages for a healthcare app’s HIPAA compliance documentation
• Create SwiftUI onboarding flow microcopy for a B2B SaaS launching at Web Summit in 48 hours
• Write accessible Flutter button labels and VoiceOver text for government contract accessibility audits
• Generate Shopify checkout page form fields and error states that reduce cart abandonment by 30%
• Draft admin dashboard empty states and success messages for enterprise SaaS shipping to Fortune 500 clients
• Write password reset flow copy for a mobile banking app during Thursday sprint planning

Benefits

• Generate 15+ microcopy variations in 90 seconds instead of writing 30+ minutes of button labels, form fields, and error messages per screen
• Ship VoiceOver-compliant iOS copy and ARIA-labeled web components that pass accessibility audits on first QA review
• Maintain consistent tone across iOS Swift, Android Kotlin, and React codebases without checking Figma comments or Notion style guides between platforms
• Write clear error messages that include recovery steps (“Try again in 15 minutes or reset your password”) instead of generic alerts (“Error occurred”)
• Cut Figma review cycles from 3 rounds to 1 by generating production-ready microcopy before designer handoff
• Create form placeholder text that shows expected format (“name@company.com” not “Enter email”) and reduces support questions about input validation

How to Use This Template

Start by defining the screen type (login, settings, checkout) and the user’s goal. The more specific your context, the better the output. For example, “user just got logged out due to inactivity” produces different error messaging than “user entered wrong password three times.” If you’re writing copy for a payment failed screen, specify whether it failed due to insufficient funds, expired card, or network timeout - each needs different recovery language.

Platform choice directly affects word count and button label formatting. iOS Human Interface Guidelines favor title case and brevity (“Sign In” as a single action), while Material Design on Android supports sentence case (“Sign in to continue”). Web forms can accommodate longer helper text under input fields, while mobile screens need concise inline validation messages. Desktop apps typically use more formal language than mobile, especially for enterprise software.

Tone impacts user trust and completion rates. “Friendly” tone works for consumer apps launching on Product Hunt (“Oops! Something went wrong. Try again?”), while “Professional” fits healthcare or banking apps where casual language reduces credibility (“Unable to process request. Contact your administrator for assistance.”). B2B SaaS products often use “Helpful” tone that explains technical concepts without talking down to users.

The accessibility options generate production-ready VoiceOver labels and ARIA attributes. VoiceOver support means every button gets context-aware labels - a “Skip” button becomes “Skip password setup” so screen reader users understand what they’re skipping. WCAG AA compliance ensures error messages have sufficient color contrast (4.5:1 minimum), keyboard navigation follows logical tab order, and form validation doesn’t rely solely on color to indicate problems. High contrast mode generates copy that works when users enable system-wide high contrast settings on Windows or macOS.

If you’re designing for multiple states (loading, success, error, empty), run this template separately for each state. Generating everything in one pass produces generic copy like “An error occurred” instead of specific messages like “Payment method declined. Update your card or try a different payment method.” Each state has different user emotions - loading states need reassurance (“Signing you in…”), success states can be enthusiastic (“You’re all set!”), and error states require calm guidance with recovery steps.

Common Mistakes to Avoid

Writing for the wrong mental state. Error messages need calm, solution-focused language that tells users what to do next (“Try again” not “Failed” or “Invalid input”). Success messages can be enthusiastic but brief (“You’re all set!” not “Your action has been successfully completed”). Empty states should guide specific action (“Upload your first invoice” not “No invoices found”). Users encountering errors are already frustrated - vague messages like “Something went wrong” without recovery steps increase support tickets.

Forgetting the next step. Every piece of microcopy should answer “what do I do now?” Error messages need recovery paths (“Check your internet connection and try again” not just “Network error”). Empty states need actionable CTAs with clear outcomes (“Import contacts from Gmail” not “Add contacts”). Tooltips should explain when to use a feature (“Enable for real-time updates” not “Enables notifications”), not just restate the button label. Loading states should set expectations (“This may take up to 2 minutes” for slow operations).

Inconsistent voice across states. If your buttons say “Get Started” but errors say “An error has occurred,” users notice the tone mismatch. Friendly apps stay friendly in errors (“Hmm, that didn’t work. Try again?”). Professional apps stay formal throughout (“Unable to process request. Contact administrator.”). Run all microcopy - buttons, errors, empty states, tooltips - through the same tone filter before shipping to production.

Accessibility as afterthought. Don’t generate copy and then add VoiceOver labels later. Screen reader users experience the product differently than sighted users - a “Skip” button with no context becomes meaningless. VoiceOver labels need full context: “Skip password setup” or “Skip to dashboard.” ARIA labels for form validation should announce errors immediately (“Email is required” read aloud when field loses focus). Color-blind users can’t rely on red text alone - error messages need icons and explicit labels like “Error:” prefix.

Generic placeholders that don’t teach. Placeholder text like “Enter text here” or “Type here” wastes the opportunity to show expected format. Good placeholders provide realistic examples that reduce form errors: “name@company.com” for email fields, “Annual revenue in USD” for number inputs, “YYYY-MM-DD” for date pickers. Users shouldn’t have to guess whether you want “John Smith” or “Smith, John” - show them the format directly in the placeholder.

Too many words on mobile. Mobile screens have limited space and users scan quickly. Don’t write “Please enter your email address in the field below” when the form label can just say “Email address” and the placeholder shows “name@example.com”. Button labels should be 1-2 words on mobile (“Sign In” not “Sign in to your account”). Tooltips need to fit on small screens - “Syncs every 5 minutes” instead of “This feature will automatically synchronize your data every 5 minutes.”

Platform-specific formatting mistakes. iOS buttons use title case (“Sign In”, “Create Account”) per Human Interface Guidelines. Material Design on Android uses sentence case (“Sign in”, “Create account”). Using the wrong case for your platform looks unprofessional. Web apps can be more flexible, but stay consistent - pick title case or sentence case and use it everywhere. Desktop apps typically match the OS - title case on macOS, sentence case on Windows and Linux.

Missing error recovery paths. Generic errors like “Invalid input” don’t help users fix the problem. Specify what’s wrong and how to fix it: “Password must be at least 8 characters” instead of “Invalid password”. Network errors should explain retry options: “Connection failed. Check your internet and try again” with a “Retry” button. Account locked messages need timeframes: “Too many attempts. Try again in 15 minutes or reset your password.”
