App developers want to launch in global app stores but localization companies are expensive. Use AI to translate app store listings, in-app text, and UI strings into multiple languages. Charge $300-800 per language for a full app localization. AI translates the strings; you ensure buttons, error messages, and navigation make sense in each language.
🚀 First Step
Download a free app, map out its UI strings, translate them into French using AI tools, and use this mock localization project as your Upwork portfolio sample.
  • Learn to work with localization file formats like JSON, XLIFF, and .strings files that developers use
  • Test translations in context by installing the app in each language to catch truncation and layout issues
  • Create a UI string glossary for each project so recurring terms like settings and save are consistent
