AppUFO
AI-translates iOS .xcstrings files into 36+ languages without breaking placeholders
AppUFO translates an iOS app's .xcstrings file into 36+ languages with AI that's aware of app context, preserves string placeholders, and respects character limits so translated text still fits the UI. You can keep specific words, like your brand name, untranslated across every language, and reverse-translate through Apple Translate to sanity-check phrases in languages you don't read. It's €9.99/month with 25,000 AI phrases included and unlimited apps, or €39.99 once if you bring your own AI key instead.

What holds up
- +Keeps string placeholders intact — translated phrases don't break formatting or interpolation
- +Character limits per phrase stop translations from overflowing your UI
- +€39.99 lifetime option lets you bring your own AI key instead of paying monthly
Mind the limits
- −Subscription caps AI phrases at 25,000/month (€9.99) or 250,000/year (€69.99) — heavy use costs more
- −Only handles .xcstrings — no mention of Android string resources or other formats
