localization
When the user wants to localize their App Store listing for international markets. Also use when the user mentions "localization", "translate my app", "international markets", "expand to new countries", "localize metadata", or "which countries should I target". For keyword research in specific markets, see keyword-research. For metadata writing, see metadata-optimization.

About localization
The localization skill helps app developers expand their App Store presence to international markets by providing a structured, expert-guided approach to app store listing localization. It addresses the common challenge of going beyond simple translation to achieve culturally adapted, market-optimized metadata that resonates with local users and ranks well in local search results.
This skill covers the full localization workflow: market prioritization using a weighted scoring framework (market size, competition, effort, revenue potential, and strategic fit), metadata localization for all App Store fields (title, subtitle, keywords, description, promotional text, screenshots, and app preview video), and cultural adaptation guidance. A key focus is the critical distinction between translating keywords and performing proper local keyword research — for example, understanding that German users search for 'Haushaltsbuch' rather than 'Budget Tracker'. The skill also includes a tiered market reference covering Tier 1 markets like the US, Germany, Japan, and Brazil, and Tier 2 markets such as Spain, India, and Saudi Arabia.
This skill is intended for indie developers, app marketing teams, and product managers who want to grow their user base internationally. It is equally useful for those launching their first localization effort or auditing an existing multi-market presence. Users considering specific keyword research for a target market or writing optimized metadata should also refer to the companion keyword-research and metadata-optimization skills.
FAQ
Do I need to fully localize my app's UI before using this skill?
No. The skill explicitly asks whether your app itself is localized or just the store listing, and can guide you on localizing only your App Store metadata even if the app UI remains in one language.
Can I just translate my English keywords into the target language?
No — the skill specifically warns against this. Local users search using different terms and concepts. For example, the German equivalent of 'budget tracker' is 'Haushaltsbuch', not a direct translation. You should run separate keyword research for each market.
How does the skill help me decide which markets to target first?
It provides a weighted scoring framework evaluating market size (30%), competition (25%), effort (20%), revenue potential (15%), and strategic fit (10%), along with a pre-built Tier 1 and Tier 2 market reference table to help prioritize ROI.
Does this skill handle keyword research for specific markets?
Market prioritization and localization strategy are covered here, but deep keyword research for a specific market is handled by the separate keyword-research skill.
What information should I have ready before starting?
You should have your App ID, know whether your app UI is localized, have target markets in mind, and know your translation budget (professional vs. AI-assisted). An existing app-marketing-context.md file is also helpful if available.
