Localizing for every country at once isn't realistic. Research takes time, and doing it badly is worse than not doing it — a keyword field stuffed with machine-translated terms actively hurts your ranking because it wastes the character budget on low-volume searches.
The right approach is to prioritize. Localize for the markets with the best combination of App Store revenue potential, search volume in your category, and competition from other localized apps.
Here's how the major markets break down in 2026.
Tier 1: Localize Here First
These markets combine high App Store spending with low competition from well-localized indie apps. They consistently produce the largest ranking gains per localization effort.
🇯🇵 Japan
Japan is the single best localization target for most indie iOS apps, for three reasons.
First, it's the third-largest App Store market in the world by revenue — behind only the US and China. Japanese users spend significantly more per capita on apps than European users.
Second, Japanese users search almost exclusively in Japanese. English metadata is invisible to them. This means the bar to enter the top results is simply: have correct Japanese metadata. Most indie apps don't.
Third, competition from localized apps is low in many categories. Western developers routinely skip Japan because the language feels intimidating. That's your opportunity.
Best for: Productivity, utilities, health & fitness, lifestyle, education.
🇩🇪 Germany
Germany is the largest App Store market in Europe by revenue. German users have a strong preference for German-language listings — a German user seeing an English-only App Store page converts at a meaningfully lower rate than one seeing German.
The keyword field opportunity here is significant. Most apps available in Germany either have blank keyword fields or use word-for-word translations of their English keywords. Researched German keywords face minimal competition in most categories.
Best for: Productivity, finance, utilities, health.
🇫🇷 France
France mirrors Germany closely — large market, low competition from well-localized indie apps, strong user preference for native-language listings. French keywords in many categories are undersaturated.
One advantage France has over Germany: the French App Store has slightly lower competition in the productivity and lifestyle categories, which means faster ranking movement after submission.
Best for: Productivity, lifestyle, education, entertainment.
Tier 2: High Volume, Fast Wins
These markets have larger user bases but lower average revenue per user. They're worth prioritizing if your app monetizes through ads or volume-based models, or if you've already covered Tier 1.
🇧🇷 Brazil
Brazil has one of the largest iOS user populations outside the US and Europe. App Store growth has been consistent for years. The key opportunity: Portuguese-language metadata is almost never done well by indie developers. Most apps in Brazil have English keywords or no keywords at all.
The trade-off: Brazilian users have lower average purchase rates than Japanese or German users. If your app is paid or has high-value IAPs, prioritize Tier 1 first.
Best for: Games, social, entertainment, utilities, ad-supported apps.
🇲🇽 Mexico
Mexico is the fastest-growing App Store market in Latin America. Spanish-language keywords for Mexico differ meaningfully from Spain — the vocabulary, idioms, and search behavior are distinct enough to warrant separate keyword research rather than sharing one Spanish localization.
Best for: Games, social, lifestyle, education.
🇰🇷 South Korea
South Korea has extremely high smartphone penetration and app spending per user. Korean metadata is done by almost no indie developers — the script barrier (Hangul) feels too high. That makes it one of the lowest-competition localization opportunities available.
The ranking gains in Korea after a proper localization tend to be dramatic, similar to Japan, precisely because the starting point is usually "completely invisible."
Best for: Games, entertainment, productivity, health.
Tier 3: Smaller but Worthwhile
These markets are smaller in absolute terms but often have strong ROI because competition is low and the work involved is manageable.
🇦🇺 Australia + 🇨🇦 Canada
English-speaking, so no translation required — but separate keyword research is still worth doing. Australian and Canadian users search with different idioms and category terminology than US users. The US keyword field applied to Australia will underperform a locally-researched one.
These are quick wins: same language, different keyword strategy.
🇸🇦 Saudi Arabia + 🇦🇪 UAE
High average revenue per user, rapidly growing app markets, almost no competition from localized indie apps. Arabic metadata requires right-to-left script support but App Store Connect handles it natively.
One localization covers both markets well (Modern Standard Arabic with Gulf dialect awareness).
🇪🇸 Spain + 🇮🇹 Italy + 🇳🇱 Netherlands
Solid mid-size European markets. Spain and Italy are worth doing if you've already covered France and Germany — similar profile, slightly smaller opportunity. Netherlands is a compact market with high per-user spending that often gets overlooked.
What to Skip (For Now)
China — requires separate App Store registration, a local entity, and government compliance. Not practical for indie developers without significant infrastructure.
Russia — payment processing and regulatory complexity have increased significantly since 2022.
India — large user base, very low average revenue per user. Worth targeting eventually for ad-supported apps, but low priority for paid or subscription apps.
How to Choose Your First 5 Markets
If you're starting from scratch, this is the order I'd recommend for most indie iOS apps:
- 🇯🇵 Japan
- 🇩🇪 Germany
- 🇫🇷 France
- 🇧🇷 Brazil
- 🇦🇺 Australia or 🇰🇷 South Korea (depending on your category)
That combination covers three of the highest-revenue non-English App Store markets, one high-volume emerging market, and one quick-win English-speaking market.
After those 5 show ranking movement — typically within 30–60 days of submission — expand to 10 markets by adding Mexico, Canada, UAE, Spain, and Italy.
The Research Question
The list above tells you where to localize. The harder part is how — which specific keywords to target in each market, what competitors rank for that you don't, and how to fit it all into Apple's character limits in a language you may not speak.
