What Is a Cross-Platform App Development Framework?

To be concise, cross-platform is a type of software that has the ability to run on multiple computing platforms i.e., Android, iOS, Windows, Blackberry, etc. The apps built on this framework do not require separate coding for each platform, rather coding once will create the foundation for the app to run as efficiently on all platforms. It is one of the most popular methods in the app development domain today, which almost all the top mobile app development services companies swear upon. 

Note: To gather an in-depth view, read this guide on cross-platform app development.

What Are The Best Frameworks For Developing Cross-Platform Mobile Apps?

1. Ionic

Ionic is one of the most remarkable and popular cross-platform app frameworks, based on AngularJS. It allows developers to use a combination of top programming languages i.e., HTML5, JavaScript, and CSS and Cordova wrapper to access native platform controllers.

Ionic enables developers to create an impeccably creative user interface along with adding user-friendly features into the app. Apps developed with this framework are highly interactive and native-like, making Ionic a perfect candidate for PWA development as well.
