5 Key steps in the localization process

Localization might seem daunting, but breaking it into manageable steps ensures success. Here’s a streamlined process:

1. Prepare your app for localization

Before diving into translations, ensure your app’s code and design are flexible. Use Unicode to support multiple languages and adopt internationalization (i18n) principles. This means:

• Designing flexible layouts to accommodate longer text in languages like German or French.

• Avoiding hardcoded strings by using resource files.

• Using placeholders for dates, currencies, and units to ensure regional accuracy.

Additionally, make sure your app’s backend can handle diverse data formats and user inputs. For instance, users in Japan might input dates differently than those in the US. By preparing your app for these differences, you save time and resources during the localization phase.

2. Translation and cultural adaptation

Translation alone won’t cut it. Your app’s tone, imagery, and messaging must feel natural to local audiences. For example:

• Replace Western-centric idioms with culturally relevant ones.

• Modify visual elements, such as icons, to avoid offensive or confusing imagery in certain cultures.

• Use transcreation for marketing materials to preserve the emotional impact of the original message.

Cultural adaptation is particularly crucial for industries like gaming or e-commerce, where user engagement heavily depends on familiarity and cultural relatability. For instance, a gaming app targeting South Korea might feature local holidays and folklore as part of its in-app events.

3. Leverage localization tools

When it comes to app localization, having the right tools can make all the difference. Here are some of the best AI-driven and collaborative tools every app developer should know about:

1. Lokalise: A platform that simplifies translation management with automation and real-time previews. It’s particularly effective for larger teams managing multi-language projects.

2. Smartling: Known for its robust integration options, Smartling provides automated workflows that connect with your development pipeline, ensuring localization doesn’t disrupt app updates.

3. Tomedes Pre-Translation Toolkit: This tool stands out by combining machine translation insights with context-aware glossaries. It enables developers to prepare localized content efficiently, ensuring higher accuracy and cultural relevance.

4. MachineTranslations.com: A platform that aggregates outputs from multiple machine translation engines, allowing developers to compare and select the most precise translation for their needs.

5. Translation Guidelines Adherence Checker: This tool is invaluable for maintaining industry-specific language quality standards. Validating translations against pre-defined guidelines minimizes inconsistencies and enhances overall quality.

6. Crowdin: Offers a collaborative environment where translators, developers, and stakeholders can work together seamlessly. It’s great for managing dynamic projects where updates are frequent.

7. Phrase: A tool that focuses on user-friendly workflows and seamless integrations, making it an excellent choice for agile teams.

These tools help automate the translation process, ensure consistency, and provide real-time feedback, reducing the time-to-market for localized apps. Leveraging a combination of these solutions can significantly enhance the efficiency and quality of your localization efforts.

Manually managing translations is inefficient, often leading to delays, inconsistent terminology, and higher costs. AI-driven localization platforms address these issues by automating repetitive tasks, maintaining a centralized glossary for consistent terminology, and integrating directly with development workflows to ensure real-time updates.

4. Test, test, and test again

Localization testing is crucial to ensure your app works seamlessly in all target markets. Pay attention to:

• Text alignment and truncation issues.

• Usability for right-to-left (RTL) languages like Arabic and Hebrew.

• Functional testing for regional settings like time zones and currency formats.

Simulated user testing in localized environments can reveal hidden bugs. For example, a weather app might display temperatures incorrectly if the regional unit isn’t set correctly.

5. Iterate based on feedback

Localization doesn’t end at launch. Monitor user feedback and app analytics to identify areas for improvement. Regular updates ensure your app stays relevant in dynamic markets.

Tools like Google Analytics or Mixpanel can be used to track user behavior across regions. If users in a specific market aren’t engaging with certain features, consider tweaking them to better align with local preferences.
