Scans every values-xx folder and diffs against your base locale. Only translates what's actually missing.
No copy-paste. Updated strings.xml files are written directly to your project.
Handles %1$s, %2$d, and other Android format specifiers correctly.
Apostrophes, quotes, and other characters are escaped correctly for Android.
Changed a string after translating? LynString detects it and offers to re-translate just that string across all languages.
Powered by Gemini AI. Supports every language and locale Android supports.
You can — for small apps. But when you're adding a new language to a project with 200+
strings, LLMs reliably miss a few. They don't have a systematic view of what's already
translated vs. missing across all your values-xx folders.
LynString diffs every locale against your base strings and only translates exactly what's missing. Nothing gets skipped.
If you've ever shipped and found a raw string key showing up in production for one specific language, you know the pain.
LynString scans your /res folder and automatically detects missing translations across all values-xx folders. Click translate, and LynString fills them in using AI. No manual copy-paste required.
100+ languages, covering everything Android supports including RTL languages like Arabic and Hebrew.
Powered by Google Gemini. Quality is high for most languages — comparable to what you'd get from a professional translation API, at a fraction of the cost.
