Hello 你好 Bonjour こんにちは Hallo ¡Hola!

For iOS & macOS developers

Localise your App in minutes

AI-powered localisation for iOS apps that understands your product

Most people don't read in English.

Every unlocalized string is a user who taps the other app instead.

The Workflow

English-Only to Worldwide in 3 Steps

Import

Drag your .xcstrings file out of Xcode and into AppUFO.

Translate

The AI reads your app description, key comments, and glossary, then translates into 36+ languages with real context.

Export

One click exports a clean .xcstrings file that drops straight back into your project. Build, submit, done.

How it Works

Drag & Drop Localisation

Drop your .xcstrings & AppUFO will do the rest

App-aware AI context

AppUFO adds product and keyword context before translating, helping AI choose words that make sense inside your app.

Glossary

Decide once how key terms translate, and AppUFO applies it consistently across every language.

Reverse Translate

Don't speak the language? Translate any result back with Apple Translate and see exactly what your users will read.

Local-first & transparent

AppUFO keeps your projects local, and translation requests are sent only to the AI provider you choose.

Why I built AppUFO

"Localizing my own apps meant hours of copy-pasting into translators that butchered my feature names and had zero clue what the app did. I wanted to import my .xcstrings file, translate everything with real context, verify the results, and export it back. That's AppUFO."

Questions, Answered

No. When you import your .xcstrings file, existing translations are preserved. AppUFO only fills in what's missing — and anything marked "Do Not Translate" in Xcode stays untouched.

Three ways: the AI translates with your app's description and per-string comments as context; your glossary locks in how key terms are handled; and reverse translate lets you convert any result back to English with Apple Translate to check it reads right.

With the lifetime license, you plug in your own API key from your AI provider. Translation costs go straight to your provider at their raw rates — AppUFO adds no markup and no subscription. You control the billing entirely.

Yes — AppUFO supports multiple app projects side by side, each with its own languages, glossary, and context. One license covers all of them.

36+ languages, covering all the major App Store markets — French, German, Spanish, Italian, Japanese, Korean, Chinese, Portuguese, Arabic, Hindi, and many more.
