How to Localize Your App Store Listing for 40+ Languages

App Store localization is one of the most underused levers in App Store Optimization. Apple supports 40 languages on the App Store, yet most indie developers only publish in English. That means they're invisible to the 60% of App Store users who search in a non-English language.

This guide covers the business case for localization, what to localize, and how to do it efficiently.

Why Localization Matters

The numbers speak for themselves:

  • Japan is the second-largest App Store market by revenue. Japanese users overwhelmingly search in Japanese — an English-only listing won't appear.
  • Germany, France, and South Korea each generate billions in App Store revenue annually, all with strong preferences for native-language content.
  • Brazil and Mexico are fast-growing markets where Portuguese and Spanish localization puts you ahead of English-only competitors.

Apple's own data shows that localized apps see 25-30% higher download rates in localized markets compared to English-only listings.

What to Localize

App Store Connect lets you localize several fields per language.

App Name and Subtitle appear in search results and are the highest-impact fields for localized keyword ranking. Your app name should include your primary keyword in each language.

Keywords get 100 characters per locale. Each locale should have a unique keyword set optimized for local search terms — direct translations often miss colloquial terms.

Description is the full app description. While it doesn't directly affect search ranking, a localized description dramatically improves conversion rate.

Screenshots are the single highest-impact conversion factor. Users who see their native language in screenshots are far more likely to download.

Preview Videos with localized captions and voiceovers increase engagement in non-English markets.

Manual vs. Automated Localization

The manual approach means hiring translators for each locale, costing $50-200+ per language with a timeline of days to weeks. Quality is high, but expensive to update when your app changes.

Machine translation through Google Translate or DeepL is fast and cheap, but App Store content requires specific expertise — character limits, keyword density, and marketing tone that generic tools don't handle well.

AI-powered translation through FrameHero uses language models fine-tuned for App Store content. Unlike generic translation, FrameHero understands character count constraints, includes locale-appropriate keywords, and maintains your brand voice across languages.

How FrameHero Handles Localization

FrameHero supports over 40 languages and automates the entire localization workflow:

  • One-click translation of app name, subtitle, keywords, and description, with each translation respecting Apple's character limits
  • Locale-optimized keyword generation that includes local search terms and colloquialisms, not just direct translations
  • Screenshot caption translation alongside metadata, so visual assets are localized without re-exporting from Figma
  • Review and edit interface showing original text alongside translations with character count indicators
  • Direct upload to App Store Connect using Apple's official APIs — no browser, no manual copy-paste

A Practical Localization Strategy

You don't need to launch in all 40 languages at once. Start with the top 5 markets: English, Japanese, German, French, and Spanish. These five languages cover the majority of App Store revenue.

Next, expand to 10-15 languages by adding Korean, Portuguese (Brazil), Italian, Dutch, and Simplified Chinese. Monitor download metrics per locale to prioritize.

Once your localization workflow is automated, expanding to 30-40 languages becomes trivial — the marginal cost of each additional language is near zero with AI translation.

Getting Started

Localization doesn't have to be a massive project. With FrameHero, you can localize your entire App Store listing into 5 languages in under 30 minutes — and push everything to App Store Connect without leaving the app.

FrameHero is available as a one-time $49 purchase for macOS, with a free 2-week trial. No subscription, no per-language pricing.
