Storefronts and localization names read from Apple’s App Store localizations reference; language codes and field limits from Google Play’s translation language list and each store’s field reference. Checked August 29, 2026.

The China mainland storefront defaults to Simplified Chinese, and Apple ties a regulatory requirement to that specific localization: where an ICP Filing Number is required, the number and the metadata must match your Simplified Chinese localization — or your primary language if you have not configured one.
It is also the densest language on the store. Three bytes per character means about 33 characters of keyword field, but each of those characters carries far more meaning than a Latin one.
Where a Simplified Chinese listing appears
Apple publishes the default language of all 173 App Store storefronts. Simplified Chinese is the default in 1 of them, and an additional supported language in 2 more.

What you translate, and what it costs you
Both stores cap the same fields, and neither cap changes by language — but the amount of meaning you fit inside them does. Apple’s keyword field is the one that surprises people: it is measured in bytes, so Simplified Han at about 3 bytes per character leaves roughly 33 characters. Google Play counts characters instead, and says so explicitly: its limits “apply to both full-width and half-width characters”.
| Store | Field | Limit |
|---|---|---|
| App Store | App name | 2–30 characters |
| App Store | Subtitle | 30 characters |
| App Store | Keywords | 100 bytes |
| App Store | Promotional text | 170 characters |
| App Store | Description | 4,000 characters |
| Google Play | App name | 30 characters |
| Google Play | Short description | 80 characters |
| Google Play | Full description | 4,000 characters |
The screenshots are part of the localization
Both stores let you upload a separate screenshot set per localization, and in practice the captions are what sells — a translated description under English screenshots converts like an English listing. Design the frames once, then export the same layout per language rather than rebuilding it: that is the difference between localizing into Simplified Chinese in an afternoon and not doing it at all.
Write it once, ship it in Simplified Chinese
Edok Studio drafts your store listing with AI, translates the whole thing — name, subtitle, keywords, description — into Simplified Chinese and 30+ other languages, and exports a screenshot set per locale from one design.
