Maximize Your App's Global Potential With AsiaLocalize

Mobile phones have become an essential part of our lives, driving a booming Android and iOS app industry. To compete and thrive in this market, app creators choose mobile app localization. A widely cited 2012 study by the app analytics firm Distimo found that localizing the text of an iPhone app lifted downloads by 128% and revenue by 26% per country in the week following the update.

String files and build integration. We work directly in your resource formats — .strings and .stringsdict on iOS, .xml on Android, JSON and YAML for cross-platform frameworks — so translated text comes back in a file your build accepts, with placeholders, plurals and formatting tokens intact. Where you ship on a regular release cycle we set up continuous localization, picking up new and changed strings each sprint instead of batching them into a single pre-launch scramble.

AsiaLocalize offers professional app localization in multiple languages, covering everything from UX/UI to app tone preservation. We help your app resonate with users worldwide, driving downloads and revenue growth.

Fast and Efficient App Localization

At AsiaLocalize, we combine cutting-edge translation technology with Asian market expertise to deliver localized apps quickly and effectively. Our tools and processes ensure quality, consistency, and on-time delivery, helping your app resonate with your target audience.

Testing before your users see it. Translated text changes length, and layouts built around English break quietly. We run pseudo-localization early to expose strings that were never externalised and fields that cannot take expansion, then test the localized build on device to catch truncation, clipped buttons, overlapping labels and mis-rendered scripts before release.

  • Advanced Tools: Translation memories, CAT tools, and Glossaries for accuracy & speed.
  • Quality and Consistency: Our process is built to consistently deliver high-quality translations & a consistent voice across all languages.
  • On-Time Delivery: We're committed to delivering your localized app on schedule.
  • Asian Market Expertise: We specialize in Asian languages and cultural nuances for app resonance with your target audience.

Culturally Relevant App Localization for Asia

AsiaLocalize helps your app seamlessly integrate into Asian cultures. We help you localize your app to ensure cultural appropriateness and an authentic user experience in over 35 Asian languages.

With our native-speaking locally-based linguists and our experienced app developers, your app will feel as if it were originally crafted in the local language of your Asian potential, fostering a deeper connection with users and maximizing engagement.

App store listings are a separate job. Your store listing is localized separately from the app itself. We adapt titles, descriptions, keyword fields and screenshot captions for each target store, because store search ranks on localized metadata — an app translated perfectly but listed in English will not be found by the users it was translated for.

Frequently Asked Questions

App localization adapts your Android and iOS app to different languages and cultures. It’s more than just translation; it ensures your app resonates with users worldwide by adjusting content, design, and functionality to local preferences maintaining cultural relevance

Internationalization (i18n) sets the stage for localization and starts earlier in the app designing stage. It’s the process of preparing and developing your app’s code to support various languages and regions without requiring engineering changes later. 

Localization (l10n) then takes over, adapting the i18n-ready app for specific target markets. It involves the engineering and linguistic changes of an internalized app to be fit for a specific locale, including translating text and modifying cultural elements. 

Think of it as internalization paves the way for app localization and app localization builds on internalization.

To decide on what countries to localize to, you need to conduct in-depth market research in the countries with the highest downloads for this type of app. You can analyze competitors, or if you have already launched the app, you can examine your current download demographics. This data-driven approach will help you prioritize localization efforts for maximum impact.

We flag it before it becomes a layout bug. Pseudo-localization during preparation shows which fields cannot take longer strings, and on-device testing after translation confirms nothing is truncated or overlapping. Where a string genuinely cannot fit, we work with your team on shorter wording rather than letting it clip.

Yes, and we treat it as a separate deliverable. Store titles, descriptions, keyword fields and screenshot captions are adapted per market, because app store search ranks on localized metadata rather than on the language inside your app.
