Translate your App Store listing into Korean
Korean (한국어) — ≈80 million native speakers, serving the App Store in South Korea. Here’s what a Korean localization is worth and how to ship one in minutes.
Why localize for Korean?
South Korea combines high iPhone adoption in younger demographics with strong spending on apps and in-app purchases. Korean-language search dominates the storefront.
App Store search is per-locale: queries typed on the South Korea storefront match against the ko localization of your metadata. Without one, your app doesn’t rank for Korean searches at all — no matter how strong your English keywords are.
Korean-specific translation tip
Korean particles attach to words, so keyword matching behaves differently — include root forms of your keywords without particles for broader matching.
StoreTranslate bakes language-specific guidance like this into its prompts, along with each field’s character limit and any custom instructions you add — brand terms to preserve, tone to match.
What gets translated
| Field | Limit (Korean included) |
|---|---|
| App name | 30 characters |
| Subtitle | 30 characters |
| Promotional text | 170 characters |
| Description | 4,000 characters |
| Keywords | 100 characters |
| What's New (release notes) | 4,000 characters |
Field-level strategy lives in our guides on translating the description and translating keywords.
How it works
- Connect your App Store Connect API key — credentials are never stored.
- Pick your app, a version in an editable state, and Korean (plus any other targets).
- Run the job. AI translates each selected field within its limit and uploads the ko localization via the App Store Connect API.
- Review in App Store Connect and submit with your next version.

Korean localization FAQ
Which App Store locale code is Korean? ＋
Korean metadata uses the ko localization in App Store Connect, covering the storefronts for South Korea.
Do character limits change for Korean? ＋
No — the App Store’s limits (30 characters for name and subtitle, 100 for keywords, 170 for promotional text, 4,000 for the description) apply to every language, including Korean. StoreTranslate validates each field against these limits before uploading.
Can I translate only some fields into Korean? ＋
Yes. Pick exactly which fields to translate — most developers start with keywords and the description, keeping the app name unchanged. Existing translations are only overwritten if you choose to.
How do I add a Korean localization in App Store Connect? ＋
Open your app in App Store Connect, select a version in an editable state, and add Korean from the language menu — or let StoreTranslate create and fill the localization for you through the App Store Connect API.
