String Catalog is a service that allows users to localize their app strings utilizng AI for accuracy. We support multiple file formats including .xcloc, .xliff, and .xcstring, offering localizations in up to 40 languages. You can learn more about string catalogs and localizing from our guide to setup your app in Xcode.

String Catalog offers tiered subscription plans to fit different needs and scales of operation. Choose from our Hobby Plan starting at $25/month, our Growth Plan at $75/month, or our Pro Plan at $125/month. Each plan provides access to a specified number of projects and strings, supporting up to 20 languages with the option for more in higher tiers. Annual subscriptions are available at a 20% discount, providing excellent value without any hidden fees.

The Hobby Plan includes up to 3,000 base language strings, the Growth Plan 7,500, and the Pro Plan 15,000 strings per month, with each string allowing up to 400 characters. These limits apply to your base language keys, meaning translations into additional languages do not count against your string key count. This structure is designed to accommodate apps of various sizes. For requirements beyond these limits, please contact us for custom solutions.

Translation involves converting text from one language to another, maintaining the original meaning. Localization goes a step further by adapting the content to suit the cultural, technical, and linguistic nuances of a specific region or audience. This process ensures that the material is not only understandable but also resonant and relevant to the target audience.

String Catalog currently supports Arabic, Catalan, Chinese (Hong Kong), Chinese, Simplified, Chinese, Traditional, Croatian, Czech, Danish, Dutch, English, English (Australia), English (India), English (United Kingdom), Finnish, French, French (Canada), German, Greek, Hebrew, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Malay, Norwegian Bokmål, Polish, Portuguese (Brazil), Portuguese (Portugal), Romanian, Russian, Slovak, Spanish, Spanish (Latin America), Swedish, Thai, Turkish, Ukrainian and Vietnamese. More to come!

The idea was born while I was developing my own iOS app, Tunely . I found it extremely tedious and time-consuming to manually copy and paste app strings back and forth from a LLM to Xcode for each language. I created String Catalog to automate the process and save time for developers.

To use String Catalog, simply create an account and connect your GitHub repository. Choose the repository where your string files are located, select the languages you want for localization, and submit your request. We will handle the localizations and submit a pull request to your repository for review. Your updated strings will be available directly within your development workflow.

While we strive to provide high-quality translations, we cannot guarantee perfect accuracy. The translations should be viewed as a starting point for localization efforts. We recommend reviewing all translated strings to ensure they meet your specific needs and quality standards.
