Ultimate Guide to App Store Localization

Localization is the key to making your app succeed globally. It’s not just about translating text - localization tailors your app’s content, design, and features to fit the preferences of users in different regions. Why does this matter? Here’s the impact:

• 128% more downloads and 26% higher revenue per country when adding a local language.

• 80% of top-grossing app markets are dominated by languages other than English.

• Apps localized into native languages see a 38% boost in downloads and better user engagement.

Localization involves adapting everything from app store listings and visuals to pricing and support. For example, a fitness app wouldn’t just translate "5 miles" into Spanish; it would convert it to "8 kilometers" for metric-using regions. Success stories like Candy Crush Saga (3 billion downloads) and World of Warships Blitz (73% increase in impressions in Spain) highlight the power of localization.

Key steps include:

1. Audit your current app store content to identify what works and what needs improvement.

2. Research markets and competitors to understand local user behavior and trends.

3. Prioritize target languages and regions based on growth potential and user data.

4. Localize metadata, visuals, pricing, and support to align with regional preferences.

Both the Apple App Store and Google Play Store offer unique localization opportunities. Apple excels in region-specific visuals, while Google prioritizes localized keywords for better search rankings. Tools like Centus, Crowdin, and Lokalise can streamline the localization process.

The US market, for instance, has specific expectations for formatting (e.g., MM/DD/YYYY dates, $9.99 pricing, and miles for distance) and cultural preferences. Testing localized versions with native users ensures accuracy and relevance.

Localization isn’t a one-time effort - it’s an ongoing process that drives downloads, engagement, and revenue. Partnering with experts like Appeneure ensures your app meets the technical and regional demands of global markets. With thoughtful execution, localization transforms your app into a global success story.

App Store Localization 101

How to Localize Your App Store Listing

Effective localization starts with careful planning, not just translation. Building a strong foundation ensures your localized content connects with the right audiences while staying consistent across all elements of your app store presence.

Review Your Current Content

Begin by auditing your existing app store assets. Take a close look at titles, subtitles, descriptions, keywords, screenshots, and video previews. This audit helps you identify which elements are performing well and which could use improvement.

Pay attention to high-performing keywords and visuals. Are certain keywords driving more downloads? Which screenshots lead to better conversion rates? These insights will guide your localization efforts, helping you retain what works while refining other areas.

It's also critical to ensure your app store listing aligns with the actual app experience. If your listing promises a polished, professional vibe but your app feels casual and playful, users will notice - and it could impact retention and reviews.

Document your findings in a clear audit sheet, noting key assets and performance metrics. This will serve as your benchmark for evaluating the success of your localization efforts.

Don't forget to consider how your current content fits different cultural contexts. Visuals, colors, and messaging that resonate in one market might not translate well elsewhere. For example, screenshots featuring predominantly Western faces or cultural references may not appeal to users in other regions.

With a solid understanding of your current assets, shift your focus to researching market trends and competitor strategies.

Research Markets and Competitors

Once you've assessed your current position, dive into market research. Analytics can help you pinpoint regions where your app is gaining organic traction. Look for patterns in user behavior, conversion rates, and retention across different countries.

Competitor analysis is another valuable tool. Download the top apps in your category for each target region and study their app store listings, visuals, and messaging. How do they tailor their content for local audiences? What keywords are they using?

Expand your research beyond your category. For example, a gaming app might learn effective localization strategies from a productivity app in the same region. Broader trends can offer surprising insights.

Keep in mind the maturity of each market and its potential for monetization. China and Japan rank as the second and third highest countries for in-app revenue after the US in the first half of 2024. This highlights the importance of targeting markets with strong revenue potential.

Choose Target Languages and Markets

Combining market research with competitor insights will help you identify the best languages and regions to prioritize. Focus on markets that align with your app's strengths and offer significant growth or revenue potential.

Start with regions where you're already seeing organic traction. Tools like App Store Connect and Google Play Console can provide valuable data on active users, conversion rates, and ratings by country. Countries with growing user bases but lower conversion rates could benefit the most from localization.

Languages like French, Italian, German, and Spanish (often referred to as FIGS languages) are commonly prioritized due to their strong economies and high purchasing power.

However, emerging markets shouldn't be overlooked. In 2024, India, Brazil, and China led the way in app downloads. While monetization might initially be lower in these regions, their massive user bases present significant growth opportunities.

Localization isn't just about translation - it often requires adapting to cultural and technical specifics. For instance, right-to-left languages like Arabic or Hebrew may require changes to your app's interface in addition to translating text.

Consider a phased approach, starting with high-priority markets. This lets you refine your localization strategy based on early results before expanding to additional regions. Remember, localization is not a one-time effort. It's an ongoing process that requires regular updates and adjustments to stay effective as markets evolve.

With your target markets and languages in place, the next step is optimizing your metadata and visuals to complete your localization strategy.

Localization Best Practices

Making your app successful in global markets takes more than just translating its text. Effective localization combines cultural adaptation, technical tweaks, and regional adjustments to create experiences that truly resonate with each audience.

Optimize Metadata and Keywords

Your app’s metadata plays a huge role in how easily users can find it across different regions. In fact, localizing app store listings into native languages can boost downloads by 38%. That’s a big deal.

Start with thorough keyword research - not just translations. Search habits vary widely between regions, even for similar app functionalities. Tools like App Store Connect’s Search Match feature can help you identify high-performing local keywords.

Your app title is another major factor in search rankings. Instead of directly translating your English title, craft localized titles that include your main keyword and clearly communicate your app’s purpose or benefit. Look into how users in each region describe similar apps and adapt accordingly.

For the keyword field, use the space wisely. Focus on single keywords separated by commas, as the App Store automatically includes plural forms. If your app targets both English and Spanish speakers in the U.S., consider a cross-localization strategy. For example, include essential English keywords in your primary U.S. listing and add additional English keywords in your Spanish (MX) metadata, as it’s also indexed in U.S. searches.

Don’t forget your app description - it should feel natural and engaging in each language. Write descriptions that connect with local users while seamlessly integrating your researched keywords. Keep an eye on performance metrics like downloads, engagement, and retention rates to see what’s working and adjust your approach as needed.

Once your metadata is polished, shift your attention to visuals that speak to local audiences.

Adapt Visual Content

Screenshots and promotional videos are key to converting users, yet they’re often overlooked in localization efforts. To resonate with different markets, your visuals should reflect local cultural preferences and norms. Start by showcasing a diverse range of people in your images - this helps ensure broader appeal.

When localizing screenshots, don’t just overlay translated text on existing images. Instead, adjust the layout to accommodate text length variations in different languages. This keeps your visuals clean and professional.

Cultural alignment goes beyond language. The colors, themes, and aesthetics in your visuals should match local expectations. For example, a color that represents good fortune in one culture might signal danger in another. Adapt your screenshots and preview videos accordingly, paying attention to pacing, music, and storytelling to ensure they align with local tastes.

Use a consistent style guide to tailor visuals for each platform while respecting local device preferences. Before rolling out visuals, test them with native users to confirm they resonate.

Set Regional Pricing and Support

After refining your visuals and keywords, it’s time to adjust pricing and support for local markets. Use tools like App Store Connect and Google Play Console to set region-specific pricing tiers that reflect local income levels and market conditions.

Offering support in local languages is equally important. Make sure your support channels align with local preferences and operate during peak hours in each time zone. Additionally, ensure your app complies with local regulations like GDPR in Europe or CCPA in California by updating your terms of service, privacy policies, and advertising practices.

A great example of successful localization is Domino’s. By tailoring its menu, pricing, and digital presence to match Indian tastes, Domino’s grew from 128 stores in 2006 to nearly 1,500 by 2021. This shows how adapting to local preferences can lead to massive growth.

Keep tracking your app’s performance - not just downloads, but also engagement, retention, and revenue per user. This will help you refine your localization strategies and focus on what works best.

Localizing for the US Market

The US is a highly competitive market, and getting the details right - both in formatting and cultural nuances - can make your app feel like it truly belongs.

US Format Requirements

When adapting for the US market, formatting plays a huge role in building trust with users. Americans have specific expectations for how information is presented.

• Currency formatting: Always use the dollar sign ($) before the number, like $9.99 or $199.99. This is non-negotiable for US audiences.

• Date formatting: The US follows the MM/DD/YYYY format. For instance, April 7, 2022, is written as 04/07/2022. Using the DD/MM/YYYY format can confuse users. If you're handling dates programmatically, store them in ISO 8601 format and convert them for display based on the US locale.

• Time representation: Americans use a 12-hour clock with AM/PM indicators. For example, 2:30 in the afternoon is written as 2:30 PM. Avoid using the 24-hour format unless your app specifically caters to technical or professional users.

• Number formatting: Commas separate thousands, and periods indicate decimals. For example, 1,234.56 represents one thousand two hundred thirty-four and 56 hundredths.

• Measurement units: The imperial system is standard. Distances are measured in miles, weights in pounds, and temperatures in Fahrenheit. That said, apps in categories like fitness might benefit from offering both metric and imperial options.

Once these formatting basics are in place, the next step is to align your app’s content and visuals with what resonates most with American users.

US Market Adaptation

Beyond formatting, successful localization means understanding the cultural and practical preferences of American users. This involves tailoring your app’s design, tone, and messaging to align with their expectations.

• Imagery and design: Use visuals that reflect American diversity and cultural settings. Photos of iconic landmarks, suburban neighborhoods, or city skylines can help users feel connected. Diverse ethnic representation in imagery is also key to reflecting the makeup of the US population.

• Language and tone: Adapt to American English spelling (e.g., "color" instead of "colour") and use phrases that feel natural to US audiences. Americans prefer direct, confident messaging with clear calls to action and value-driven statements.

• Legal and regulatory considerations: Ensure compliance with US-specific laws. Privacy policies should reference relevant US regulations, and terms of service must meet both state and federal requirements.

• Payment and pricing: Americans are familiar with psychological pricing, such as $9.99 instead of $10.00. Subscription models are also widely accepted. Make sure to integrate popular payment methods like Apple Pay, Google Pay, and major credit cards. These details not only meet user expectations but also enhance trust and engagement.

Test with US Users

Testing your localized app with actual US users is a critical step to ensure your efforts hit the mark. This helps uncover any issues and refine your approach before launch.

• Beta testing: Use tools like TestFlight to share your app with a group of native speakers. Their feedback can highlight subtle errors in language or formatting.

• A/B testing: Experiment with different titles, descriptions, and visuals to see what resonates most with American users.

• Monitor performance: Track engagement metrics and technical performance to identify areas for improvement.

"Once your app is localized, use TestFlight to share your app with a group of users in the market to get feedback and gather opportunities for improvement".

An iterative improvement process is key. Use testing data to refine your localization strategy, monitor keyword performance, and respond to user feedback on language and cultural relevance. This continuous adjustment ensures your app stays aligned with user expectations.
