App Store localization languages by country

Which languages does each App Store country support?

Every App Store storefront (the store of one country or region) has a default language, and many also have additional supported languages. App Store Connect Help publishes the full list: 175 storefronts, of which 104 have at least one additional language and 71 have English (U.K.) only. The table below copies it as Apple writes it.

Apple's wording matters. The help page calls these the default language and additional supported language(s) of each storefront. It does not use the word "indexed". What Apple says about search is on a different help page: people can search for your app using localized keywords in all countries or regions where the App Store supports that language.

What languages can App Store metadata use?

App Store Connect Help lists 50 languages and locales for metadata:

Arabic, Bangla, Catalan, Chinese (Simplified), Chinese (Traditional), Croatian, Czech, Danish, Dutch, English (Australia), English (Canada), English (U.K.), English (U.S.), Finnish, French, French (Canada), German, Greek, Gujarati, Hebrew, Hindi, Hungarian, Indonesian, Italian, Japanese, Kannada, Korean, Malay, Malayalam, Marathi, Norwegian, Odia, Polish, Portuguese (Brazil), Portuguese (Portugal), Punjabi, Romanian, Russian, Slovak, Slovenian, Spanish (Mexico), Spanish (Spain), Swedish, Tamil, Telugu, Thai, Turkish, Ukrainian, Urdu, Vietnamese.

Apple's list writes "Slovenia"; the storefront table writes "Slovenian".

Storefronts with additional supported languages

Storefronts with English (U.K.) only

These 71 storefronts have English (U.K.) as the default language and no additional language in Apple's table:

What patterns stand out in the table?

• English (U.K.) is almost everywhere. It appears in 172 of 175 storefronts. The three exceptions are the United States (English (US)), Canada (English (Canada) with French (Canada)) and Japan (Japanese with English (US)).
• Türkiye's default is English (U.K.). Turkish is listed as the additional language, not the default.
• One Spanish for the Americas. Spanish (Mexico) is the default in Mexico and most of Latin America, and an additional language in the United States, Belize and Uruguay. Spanish (Spain) appears only in Spain.
• Portuguese splits by country. Portuguese (Brazil) is the default in Brazil and additional in the United States; Portuguese (Portugal) appears only in Portugal.
• French is the most common additional language. French appears in 32 storefronts; French (Canada) only in Canada.
• The widest lists. India has 11 additional languages; the United States has 9.

Which localization does a user see?

Apple explains the rule with an example: your primary language is English and you add French.

1. People whose device language is French see the French localization.
2. People in storefronts where the App Store supports French but not English also see French.
3. People can search for your app with your French keywords in all storefronts where the App Store supports French.
4. If no localization matches, the next most relevant one is used; elsewhere your primary language shows.

Apple also notes that the language shown can vary with device and system settings.

Can I use an extra localization for more keywords?

This is a common practice, not an Apple recommendation. In a storefront with two or more languages, developers fill the keyword field of an additional localization as well, so the app can be found for more terms. In the United States that could be the Spanish (Mexico) localization; in Türkiye, a Turkish app may fill both Turkish and English (U.K.).

What Apple confirms: localized keywords are searchable in every storefront that supports that language. What Apple does not say: how much weight a second localization's keywords get, whether words combine across localizations, or whether it equals the primary language. Each localization has its own keyword field of up to 100 bytes.

The risks are real, and they follow from Apple's own rules:

• Real people read it. Keywords are hidden, but the localization's name, subtitle, description and screenshots are shown to everyone whose device uses that language. A Spanish-speaking user in the United States sees your Spanish (Mexico) page.
• It travels. A localization is used in every storefront that supports its language. Spanish (Mexico) is the default across most of Latin America, and English (U.K.) appears in 172 storefronts. Keywords written for one country land in all of them.
• Relevance rules still apply. Apple names irrelevant terms, competing app names and trademarks as common keyword rejection reasons. Keywords must describe your app in every localization.
• Do not repeat. Apple says not to repeat words from your name, subtitle or category in the keyword field, and to skip plurals of words you already have. It does not document repeats across localizations; in practice, use each field for new terms.

Measure it like any other change: track the added terms in that storefront for a few weeks before and after.

How do I use the table for my app?

1. Find the storefronts you care about in the table.
2. For each one, note the default and additional languages.
3. Decide which localizations you will write for real users first; those are the ones people will read.
4. Research keywords per storefront, in that storefront's own autocomplete.
5. Fill each localization's name, subtitle and keyword field; mind the 100-byte limit (accented letters take 2 bytes).
6. Track ranks per storefront after release.

The wider method is in app store localization, country priorities are in which countries to localize first, and field rules are in the App Store keyword field.

How does Uptika help?

There is no store-language map tool in Uptika; this page is the reference. To check one term across markets, use the free Keyword Atlas: up to 10 countries on both stores, with popularity, difficulty and the top 3 apps in each. To track ranks per storefront every day, create a free account.
