  • As iOS and Android can be built from one codebase, developers can be more productive.
  • Material design provides a high level of customization.
  • Customize OEM widgets to create branded designs.

2. React Native

There is no question that React Native is one of the best app frameworks for cross-platform development. Cross-platform development is a well-known feature of React Native, which is widely used for iOS and Android. In 2015, Facebook brought it into existence and since then its developer community has grown tremendously.

Platforms such as Android and iOS feel native with the help of the framework. The framework is built on JavaScript. Using React Native, developers can create UI interfaces more easily since it is built on JavaScript.

Though it is built with JavaScript, React Native does not use HTML technologies like WebView, CSS, or HTML technology. As a replacement, the platform uses poly fills that resemble CSS and JSX. React Native does not have a DOM API either.

React.JS and JavaScript combine to form this cross-platform app framework’s main draw. In addition, developers have the option of using Java, Swift, or Objective-C for certain parts of the app.

Hallmarks of ReactNative:

  • Your app is more likely to reach the app store faster
  • Using modern web technologies, the architecture is modular and intuitive
  • Support that is community-based, therefore excellent

3. Ionic

The most remarkable Ionic app development framework is AngularJS-based, cross-platform. Adam Bradley, Max Lynch, and Ben Sperry first built it in 2013 as an open-source cross-platform app framework. Apache Cordova and AngularJS were Ionic’s main components.

Ionic applications created using the Apache Cordova framework are hybrid HTML apps according to the Apache Cordova principles. These apps can only be used on your smartphone devices because they run in a special shell. WebView runs the Android application and UIWebView runs the iOS application.

Developers can build user-centric apps with Ionic thanks to its user-friendly features and creative user interface. Users stay immersed in the app long after it is launched because the user interface is so pleasing to the eye. This cross-platform app framework is used in PWA development because its applications closely resemble native apps.
