What is a Cross-Platform App?

A Cross-Platform Mobile App is an app developed using a library that allows development to occur in one language which is then complied to Native Code. 

A developer can write the application in JavaScript if using React Native or C# if they use Xamarin. 

This allows the developers to write the code base once, make tweaks for each platform and have two applications developed simultaneously. The app’s performance is as good as a Native Mobile App as that is what the final output of the App becomes. If you are not doing cross-platform development or hybrid mobile application, then you’re writing two applications, one for iOS and one for Android, in two different languages.

Some Cross-Platform mobile frameworks are

  • React Native
  • Xamarin
  • Flutter
  • PhoneGap
  • Ionic
