String Catalog

What is String Catalog?

String Catalog is a localization tool designed for iOS and Android development teams that want to streamline app string management within their existing Git workflow. It supports .xcstrings for iOS and strings.xml for Android, allowing teams to localize app strings, release notes, and store metadata directly through GitHub, GitLab, or Bitbucket. The product eliminates the need for spreadsheet cleanup, broken builds, or one-off scripts by integrating seamlessly with source control.

Key features include branch-based reviewable updates, human reviewer support with secure no-login review links, and tone guidance to maintain brand voice. Teams can protect brand terms, add context for reviewers, and retry low-confidence output before release. String Catalog handles App Store and Google Play release notes and store listing copy, generating localized content with platform-specific field limits and locale handling.

Benefits include reduced overhead, faster release cycles, and improved quality. By keeping Git as the source of truth, teams avoid silent content mutations and maintain a clean diff history. The product is built for safe, reviewable changes, with manual edits, review queues, suggested fixes, and bulk acceptance features.

Use cases include mobile app teams shipping regular updates, indie developers managing multiple languages, and enterprise teams requiring compliance and audit trails. Technical details include support for Git providers, branch-based workflows, and exportable outputs for growth teams.

String Catalog offers one free language with no credit card required, making it easy to evaluate. It is designed for teams that trust their release process but want to remove localization overhead. Whether you are shipping a weekly build or a major release, String Catalog ensures your app sounds like your product in every language.
