Cresc

    Cresc - Professional Over-the-Air Update Solution

    Cresc (npm package: react-native-update npm version) is a professional Over-the-Air (OTA) update service for React Native teams shipping globally. It is designed to keep release workflows lean, stable, and cost-efficient from small apps to large production fleets.

    Recommended integration path

    If you use an AI coding tool that supports Skills, start with Install & Use Skills. Install the react-native-update Skill first, then let AI adapt the integration to your existing React Native or Expo project. The manual docs remain the fallback for brownfield apps, monorepos, and projects that need line-by-line review.
