Locale Coverage Checker

Apple indexes each localization of your listing separately, and every localization carries its own app name, subtitle, and 100-character keyword field. An app localized into 20 languages therefore has up to 20 × 160 characters of indexable keyword real estate; an English-only app has one set. Coverage gaps are not just a conversion problem — they are missing ranking surface in every storefront that reads those locales.

Coverage audits also expose a common mistake: developers who translated the app binary but never localized the store listing. The app works in German, yet German users see an English product page and English screenshots. Because the listing localization is managed independently in App Store Connect, this checker reads what the store actually serves, not what the app supports internally.

When two apps compete for the same keywords, the one with a native-language listing almost always wins the locale-specific queries — localized titles and subtitles simply match what local users type. Checking the coverage of your top three competitors tells you where the playing field is level (everyone localized), where it is hostile (they localized, you did not), and where it is open (nobody localized).

Open locales are the interesting ones. A mid-size market like Turkey, Poland, or Thailand with zero localized competitors can deliver better download-per-effort returns than fighting incumbents in English. Pair the coverage gaps you find here with the Locale Priority Planner to rank them by revenue potential before committing translation budget.
