Mobile App Localization for iOS and Android

Want your mobile app to become popular worldwide? Without quality localization into the target audience’s languages, that’s almost impossible. Users quickly delete apps whose interfaces they don’t understand. Localization allows you to reach millions of new users and significantly boost your revenue.

iTrex Language Services offers professional translation and full localization services for iOS and Android apps. We don’t just translate text—we adapt your product considering cultural nuances, technical platform requirements, and the expectations of local users.

Why Do You Need Professional Mobile App Localization?

Localization is an investment that pays off multiple times. By adapting your app for different countries and cultures, you gain:

1. More positive reviews and higher ratings. Users appreciate being able to work with an app in their native language. This directly impacts your ratings on the App Store and Google Play.
2. Expansion into new markets and a substantial increase in your user base. Each localized language opens your app to a huge audience eager to become active users.
3. Strong competitive advantage. Localized products rank higher in app stores, attracting more attention compared to untranslated counterparts.
4. Increased conversions and revenue. Statistics show localization can boost conversion rates by 25-30%. Users are willing to pay for the convenience of using an app in their native language.

Why Trust iTrex with Your Mobile App Translation?

We have over 18 years of experience working with localization of complex IT projects. Over the years, we’ve developed an approach that guarantees high quality and effective localization:

• Comprehensive adaptation: We translate not only the text but also adapt the interface (UI/UX), graphics, audiovisual elements to regional cultural norms and technical specifics.
• Accuracy and naturalness: Our projects are handled by native speakers who not only know the language but also understand the cultural context and slang of the target audience.
• Multi-stage quality control: Every translation goes through a control system: translator – editor (meaning, terminology) – proofreader (grammar, spelling) – stylistic reviewer (style, brand tone) if needed.
• App Store and Google Play descriptions: We translate and optimize app store texts to improve your product’s visibility and encourage downloads.
• Data security: We strictly adhere to confidentiality and are ready to sign a non-disclosure agreement (NDA).
• Free sample translation: Ensure the quality of our services before making a decision. We will translate a small fragment of your app free of charge.

How We Translate and Localize Mobile Apps: The Process

Our localization process is built on transparency and efficiency:

1. File receipt and analysis: You send us your app’s text files in a convenient format (strings, XML, HTML, Excel, etc.). Our specialists analyze the volume, structure, and specifics of the texts.
2. Project setup in CAT tools: We upload texts into a modern translation support system (CAT), which allows us to efficiently reuse previously translated segments (translation memory), maintain terminology (glossaries), and enable team collaboration.
3. Text translation: The project is handed over to translators specializing in your industry and working with the required language pairs. Native speakers are involved if necessary.
4. Editing and proofreading: Translated texts undergo thorough review by editors and proofreaders to identify and fix semantic, terminological, grammatical, and spelling errors.
5. Graphics and multimedia localization: If your app contains images with text, audio files, or videos, we translate and adapt them accordingly.
6. Localization testing (LQA – Localization Quality Assurance): The most critical stage! Our testers install the localized app on real devices (iOS/Android) and verify the correctness of text display (no truncations, overlaps), link functionality, and contextual accuracy.
7. Project delivery and updates support: You receive the localized files. Thanks to the CAT system, when your app updates, we only translate new or changed segments, saving you time and money.

Specifics of Translating and Localizing Mobile Apps

Mobile app localization has its unique features that we always consider:

• UI/UX constraints: Text length can vary greatly when translating into another language (e.g., from English to German). We work to ensure the translated text displays correctly on buttons, menus, and other UI elements without breaking the design. This is a key aspect of app interface translation.
• Cultural adaptation: It’s not just about translating words but also adapting content (images, color schemes, examples, jokes, measurement units) so that it’s understandable and non-offensive to the local audience. Our native-speaking translators are familiar with these nuances. This is what mobile app adaptation is all about.
• Handling variables and code: We know how to work with localization files containing variables, placeholders, and code elements without damaging their structure.
• Glossaries and translation memories: Creating and using glossaries (lists of specific terms) and translation memories (databases of previously translated segments) ensures terminology consistency throughout the app and speeds up updates.

Technologies and Formats for Mobile App Translation

Our work’s efficiency and quality are achieved through the use of modern technologies:

• CAT tools (Computer-Assisted Translation systems): We utilize leading CAT tools that enable working with translation memories, glossaries, automatic quality checks, and easy management of large texts and updates.
• Handling various file formats: We accept and process standard localization formats for iOS and Android such as .strings, .xml, as well as texts in .html, .xliff, .csv, .xls/xlsx, and other formats. You simply provide the files, and we handle the rest.
• Localization testing tools: Our QA specialists use emulators and real devices to thoroughly test the display of translated text in the interface.

Project Example: Translation of the Trend Micro Website

Client: Trend Micro – a cybersecurity software producer.
Industry: Antivirus software.
Services: Website translation, proofreading, and correction (no extra charge).
Languages: (Only the direction of translation is specified) The source language is not specified but is assumed to be translated into Russian or another language different from the original language of the Trend Micro website.
Project features: Complex XML format of source texts with many embedded tags, complicating preparation for translation. Limited preview access to the final translated version.
Outcome: The project was completed on time, maintaining style and accurately conveying the meaning.
