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.

Traditional Chinese is the default language of the Hong Kong, Macau and Taiwan storefronts — three separate markets that share one Apple localization, which makes it unusually efficient to add.
Play splits it further into zh-TW and zh-HK, and the two do differ in vocabulary; if you can only produce one, zh-TW is the broader default.
Where a Traditional Chinese listing appears

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 Traditional 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 Traditional Chinese in an afternoon and not doing it at all.
Write it once, ship it in Traditional Chinese
Edok Studio drafts your store listing with AI, translates the whole thing — name, subtitle, keywords, description — into Traditional Chinese and 30+ other languages, and exports a screenshot set per locale from one design.
