In today’s interconnected world, app developers have an incredible opportunity to reach a global audience. Building an app that can penetrate the global market is an ambition of many app development agencies.

Internationalization and Localization

However, to truly tap into this global market, you need to be aware of the internationalization-vs-localization debate and what both processes stand for:

  • Internationalization (i18n) refers to the process of designing and developing an app in a way that makes it easy to adapt to different languages and cultures.

  • Localization (l10n), on the other hand, is the process of adapting an app to a specific language and culture.

This article covers the core benefits of internationalizing and localizing your apps as well as some proven best practices for implementing both processes with confidence.

Benefits of Internationalization and Localization for Developers

While internationalization and localization may seem like daunting tasks, they are essential for developers who want to expand their skills and succeed in the global market. These are just a few of the benefits of i18n and l10n.

Benefits of Internationalization and Localization for Developers

Increased reach

By making your app available in multiple languages, you can exponentially increase your potential user base. This can lead to increased downloads, app reviews, and brand recognition, ultimately propelling your app’s success in the international arena.

Improved user experience

Language barriers can hinder user engagement and understanding, leading to frustration and potential abandonment of the app. Localized apps, on the other hand, provide a more seamless and enjoyable experience for users, as they can interact with the app in their native language and cultural context.

By localizing your app, you remove these barriers and create a more intuitive and engaging experience for users worldwide. This can boost user satisfaction, loyalty, and advocacy, driving positive word-of-mouth and further expanding your app’s reach.

Enhanced brand reputation

Consumers are increasingly discerning and appreciate companies that demonstrate cultural sensitivity and a genuine interest in serving diverse markets. By prioritizing i18n and l10n, you project a positive brand image, fostering trust and loyalty among users worldwide. This enhanced brand reputation can translate into increased customer retention, positive media coverage, and a competitive advantage in the global market.

Increased revenue

With a larger user base and a better user experience, you can potentially increase revenue from in-app purchases, subscriptions, or advertising. A localized app can attract more users, leading to a larger pool of potential customers for in-app purchases and subscription services.

Additionally, localized advertisements can resonate better with users, potentially leading to higher click-through rates and increased revenue from advertising campaigns. By expanding your user base and enhancing the user experience through i18n and l10n, you open up new revenue streams and boost your app’s overall profitability.

Tips for Implementing Internationalization and Localization

Here are a few tactics that can help you take your apps to the next level.

Strategic planning is key

By adopting a global perspective from the very beginning of your app development process, you can streamline workflows, save time and resources, and ensure a smooth transition to global markets:

  • Start by adopting a development approach that inherently supports i18n. This includes using Unicode for text encoding, separating code from language-specific content, and designing user interfaces that can accommodate different languages and text sizes.

  • Early on, define the specific target markets and languages you intend to support. This will guide your translation efforts and ensure that your app caters to the cultural nuances of each market.

  • Leverage localization tools to manage the translation and localization process efficiently. These tools can automate translation tasks, track progress, and ensure consistency across languages.

  • Implement a comprehensive globalization testing strategy to identify and resolve any language-related issues before launch. This includes testing text rendering, date and time formats, currency symbols, and cultural sensitivity.

Technology is your ally

A plethora of localization tools can simplify and streamline the i18n and l10n process, making it more manageable and cost-effective:

  • Translation management systems (TMS) provide a centralized platform for managing translations, including tasks such as creating translation projects, assigning work to translators, and reviewing and approving translations.

  • CAT tools utilize translation memories and terminology databases to improve translation consistency, reduce time spent on repetitive tasks, and maintain a consistent brand voice.

  • Globalization testing tools automate the process of identifying and resolving functional or language-related issues, ensuring that your app works properly across different languages and locales.


Cracking the code of internationalization and localization may seem like a challenge, but the rewards are well worth the effort. By making your app accessible to a global audience, you can open up new markets, improve user experience, and boost your bottom line. So, what are you waiting for? It’s time to start your i18n and l10n journey and unlock the full potential of your app.
