AppUFO

AppUFO is a macOS app that helps iOS developers translate their apps into multiple languages without the usual headache. Instead of manually editing .xcstrings files or hiring expensive translators, you drop your localization file into AppUFO, and it uses AI to generate translations for 36+ languages. The key trick: it preserves placeholders like %@ and %d, so your app's UI doesn't break after translation. You can also set character limits to keep text from overflowing buttons or labels.

How does it work? You drag your .xcstrings file into the app, choose target languages, and AppUFO handles the rest. It understands app context — for example, it knows that "Home" in a tab bar is different from "Home" in a settings menu. You can protect brand names or specific terms from being translated, and use the reverse translate feature to check translations in languages you don't read. The app runs entirely on your Mac, and you can either use the built-in AI (subscription includes 25,000 phrases per month) or bring your own API key for more privacy.

This tool is built for iOS developers who want to reach international users without spending weeks on localization. Indie developers will appreciate the simple drag-and-drop workflow and the lifetime license option. Localization managers can batch-translate multiple apps and verify output with the reverse translate feature. If you're shipping an app to the App Store and want to compete in non-English markets, AppUFO cuts the process from days to minutes.
