String Catalog - Automate iOS & Android Localization

How It Works

Three Simple Steps to
Automated Localization

Streamline your Xcode localization and Android string file workflows.

Connect Your Repo

Authorize String Catalog on GitHub, select your repo & branch, and we'll automatically scan for .xcstrings or Android XML files.

Configure & Localize

Pick up to 40 target languages, set tone & custom prompts if needed, then hit "Localize". We'll handle the rest.

Review & Merge

Instantly receive a PR with translated strings. Review in GitHub and merge every new push keeps translations in sync.

Best Choice

String Catalog Recommended

Up to 12 hours saved per release

Set it and forget it - focus on what matters

✓ Zero maintenance ✓ Always up to date ✓ Custom tone & glossary ✓ Format validation ✓ Best practices built-in ✓ Just 15 minutes total

Custom localization scripts

~7-9 hours saved per release

Build once, maintain forever

⚠️ Script maintenance ⚠️ API version updates ⚠️ Bug fixes & edge cases ⚠️ Format changes ⚠️ Team onboarding ⚠️ Takes 3-5 hours

Manual localization

0 hours saved per release

No time savings

Painful every single time

❌ Extract strings manually ❌ Spreadsheet management ❌ Email back-and-forth ❌ Format validation ❌ Copy-paste errors ❌ Takes 8-12 hours

That's 6+ weeks of dev time saved each year for a typical indie app

Based on monthly releases to 10+ languages. More releases = more time saved.

Why teams choose String Catalog

Maximum time savings with zero maintenance burden
Costs less than a few hours of developer time per month
Always up-to-date with platform changes

The hidden cost of DIY

Custom scripts need constant updates for new OS versions, API changes, and edge cases. That "quick script" becomes a maintenance nightmare that steals time from feature development. Let us handle the complexity while you ship.
