What Is App Localization?

App localization is the process of adapting an app to a particular language, market, culture, and the corresponding desired look and feel.

The process of customizing your mobile app to work in other languages can include spoken variations and dialects of the same language. The app must also suit the culture and other regional attributes. App localization is not just a translation of the language but reflects a change in content and layout catering to any country.

The top app localization services include:

  • Localization of mobile, web apps, and software
  • Platform, API, and integrations
  • Cloud-based localization process
  • Mobile app localization testing

Mobile App Localization Vs. Mobile App Internationalization

App internationalization is the process of customizing the code to make your app ready for the time localization happens. It involves taking care of font style, language orientation, content displays, and other minute details to deliver an in-sync user experience, irrespective of the users' background.

On the other hand, app localization is the process of rendering your app content to different languages and customizing other elements of the app, such as screenshots and preview videos, according to your target audience.

App Localization vs. App Translation

App translation is changing the text of the app into another language.

App localization refers to language translation plus using locally relevant graphics, units of measurement, colors, social networks, etc.

Main Considerations When Localizing An App

The essential factors to keep in mind when localizing a mobile app are:

  • Language: The text of your app should be translated accurately into the target language(s).

  • Interface: The user interface of your mobile app should be adapted for different regions. For instance, you may need to use different date formats or currencies.

  • Culture: You should take into account cultural differences like design preferences and social customs.

  • Legal requirements: There can be legal requirements governing how your mobile app can be used in certain countries. Ensure you are aware of the legal requirements and that you are compliant with them.

  • Marketing: You will need to create localized marketing materials like website translations, ads, and social media posts.

Mobile App Localization Benefits

App localization improves the user experience for your global audience and expand beyond the English-speaking market. Here are the detailed benefits of mobile app localization.

Access To Global Reach

A multi-language app gives you better access to the global market in terms of exposure. This will help you to reach as many people as possible and improve your user ratings.

Sales Potential

With app localization, you can expand your reach by ensuring it's also available to markets based overseas. This is an excellent way to boost your downloads and ensure you provide all users with an improved user experience.

Better ROI

Increased ROI is guaranteed with the right mobile app localization strategy if implemented correctly, as app localization expands the target market, thus increasing the reach and downloads of your app.

If that's not enough to convince you, here are some mind-blowing stats:

  • The United States, China, and Japan are far ahead of the rest of the world in total app revenue generation. If you are not targeting these markets, you are potentially losing out on significant revenue.
  • Businesses that localize their iOS apps saw a whopping 128% more downloads than their peers who didn't.
  • In the Google Play Store, 80% of countries in the top five for downloads and revenue are non-English speaking countries.

App Store Localization

App store localization is the practice of localizing the elements on the app's product page for a target market.

iOS App Localization

The Apple App Store supports 28 localizations, including Danish, Dutch, Chinese, English, German, Greek, and French. All parts of your product page need to be localized, including every section of the text. All images should be considered appropriate for the users as this can differ between cultures.

Ensure you closely study the local audiences in detail when it comes to app store localization using the right search terms. The correct translation of your app's name, keywords, and description will help local users find it more easily.

Android App Localization

There are approximately 77 different localizations available on Google Play. Identifying the best possible target markets for your business is essential at this stage, as localizing for all 77 languages can be difficult.

For app store optimization, you need to add a localized version of the app title and short and long descriptions in the Google Play Console.

Android apps run on several devices across different regions, so your app should handle text, numbers, currency, audio files, and graphics correctly to be fully localized.

How To Localize A Mobile App?

The process to localize a mobile app involves using the right set of skills, technical expertise and tools. Here is an in-depth list of steps to localize your app in the best way possible:

Externalize Your Mobile App

It's one of the first steps toward the process of app localization. Your mobile app resources and assets not just consist of code but also other data files such as tutorials, images, videos, etc.

So, to successfully localize your app, ensure you are correctly externalizing these assets so that it's easy to create the translated versions of each file.

Layout The Whole Process

When adding a localization facility to your app, ensure that the layout is prepared well in advance, so you have a clear idea of the structure you must follow while getting your app localized.

When creating the layout, keep track of the length of the words getting translated. This way, you will be able to keep note of the space the translated words are taking compared to the words of your source language.

App Content

Localizing your app's content will help you engage with your users better. Localization of app content such as date, time, units, editorial content, and alternative SDKs will help you a lot to connect with your target audience. You need to ensure that each of the content pieces in your app provides a localized experience to the users (including emails!)

Location-based Push Notifications

You should personalize your push notifications based on the location of your user. For example, you can use push notifications to allow your app users to know of those who have just joined your app from a nearby location. Stimulating curiosity and competitiveness by knowing who has recently joined an app from a nearby location will bag you an app session.

User Activity Feeds

Encourage your app users to share their milestones on in-app activity feeds. Let them look at each other's accomplishments in the app, where and how they have achieved them so far. This will help you nudge your app users to try their hand at the same tactics, resulting in an increase of your app usage. You can also use activity feeds to monitor how your app users use your app and offer location-specific tips that will help them to use your app more effectively.

Support Pages

Ensure that your support pages and other links in your app that help your app users access information are localized so that they can get the information in their native language. This will help you resolve user issues before your users get disengaged from using your app.

Test Your Mobile App

Once the process of app localization is completed, you need to test your mobile app thoroughly. It is necessary to carry out linguistic testing along with another localization testing to identify content and layout-related issues and errors.

Try to use the localized app on different devices with different screen sizes to counter bugs and other errors.

App Store Optimization For Mobile App

App store optimization (ASO) is a way through which you can refine your app store content so that users can find and download your app with minimal effort. You need to research your target markets before optimizing your app store's contents and search terms commonly searched for in the app store for apps similar to yours.

To make the local users find your app with utmost ease and comfort in the app store, you need to do a good job by translating your app's title along with working on keywords, descriptions, screenshots, and more.
