App Developers in San Francisco FAQ
Which 3 Mobile App Frameworks Are Best for App Development?

In mobile app development, a framework is important because it’s the technology foundation that supports your app and allows you to build certain features. Mobile app components fit and work within a framework, and there are several developers uses for mobile app development:

  1. React Native

React Native: When building mobile apps for iOS or Android, developers find React Native exceptional for building native apps without sacrificing the user experience. Developed by Facebook, React Native is used to build various applications on mobile and web platforms.
