Yolande Grant, Editor-in-Chief

The most important thing for me is that Nitro uses only native translators. Texts translated by such linguists sound more authentic, which adds much more credibility to our products. This is critical for translating texts for our websites, as well as Ebay and Amazon platforms.

Cinta Punto

Andrii Bychkovskyi, CEO

It works great for translating small texts into many languages ​​at once. Instead of running around and searching for translators, you can just copy and paste the text, and in like half an hour, you get an email notifying you that the text has already been translated into 3 languages. It's pretty much a perfect self-service.

Alexey Dmitriev, CEO

We tried working with freelance translators, but it was time-consuming and far from efficient. We switched to Nitro completely, because with Nitro the translations are ready quickly — as soon as in 2 hours — and all the questions regarding game-specific details are conveniently handled with a manager in the chat.

We used to work with freelance translators via a crowdsourcing platform, but the process was lengthy and complicated.

FAQs About Apps Translation

Comparison Aspect

Android Localization

iOS Localization

File formats

Uses XML files for storing localized strings (strings.xml).

Uses .strings files, which are plain text files containing key-value pairs.

Resource organization

Localized resources are placed in separate folders named after the language and region (e.g., values-en, values-fr).

Localized resources are grouped in .lproj folders (e.g., en.lproj, fr.lproj).

Pluralization rules

Supports detailed pluralization rules based on quantity (e.g., one, few, many, other).

Pluralization is less flexible and may require workarounds, such as using multiple string keys.

Default language

The default language is set in the values folder and applied if no specific localization is available.

The default language is determined by the base internationalization or fallback mechanism.

Text length adaptation

Allows dynamic adjustments using flexible layouts like ConstraintLayout for text resizing.

May require manual resizing or auto-shrinking configurations, especially for fixed-size UI elements.

Build tools

Localization is integrated with Android Studio’s tools, such as the Translations Editor.

Xcode provides built-in tools like the Export for Localization and Export for Localization.

Date/time format

Relies on the system's Locale settings or custom DateFormat patterns for localization.

Relies on NSDateFormatter or DateFormatter for localized date and time formats.

Language codes

Uses BCP 47 language tags for locale identification (e.g., en-US, fr-CA).

Uses similar language tags but requires explicit management for certain regional variants.

Testing localization

Provides tools like LocaleConfig or emulator settings to test different locales.

Allows testing localized versions directly in Xcode or through device settings.

Third-party libraries

Often integrates with libraries like Google Play’s Translation Service for managing translations.

Commonly integrates with Apple frameworks like NSBundle and third-party services for managing strings.
