String Catalog

String Catalog is an app localization product aimed at iOS and Android teams. According to the page, it connects to GitHub, GitLab, or Bitbucket, lets teams pick the branch they release from, and delivers localization changes as reviewable updates. It supports Apple .xcstrings and Android strings.xml files, and also covers App Store and Google Play release notes and store listing metadata. Teams can choose languages, add tone guidance and glossary rules, and use human review tools such as secure no-login review links and review queues. The page states a free option of one language with no credit card required, and links to a pricing page and a cost calculator.
