String Catalog

Push a new string to your iOS or Android app, and String Catalog translates it and sends the result back to your repository as a pull request.

String Catalog is an app localization platform that automates translation for mobile apps, with a GitHub integration that handles unlimited pull requests on every plan.

There are three paid tiers.

Hobby costs $15 a month and covers unlimited apps, up to 40 languages, 3,000 base string keys and 20 localized release notes per month.

Pro is $45 a month and raises the key limit to 7,500, adds unlimited release notes, localization accuracy monitoring and team support.

Business is $75 a month with 15,000 keys and the same Pro features.

Support response time is 48 hours on Hobby and 24 hours on the higher plans.

The main catch is the key cap, so check your string count before choosing a tier.

Translations are fully automated, and String Catalog localizes new strings as your app changes.
