Ionic app development framework makes cross-platform app development much easier as compared to others. It is an open-source app framework which is licensed under MIT. For translation to native apps, Ionic uses HTML5. In terms of design and structure, Ionic is quite similar to AngularJS. With Ionic, developers can build apps for iOS and Android. Additionally, they can develop PWAs, i.e., progressive web apps.

Some appealing features of Ionic cross platform framework are:-

  • Based on SAAS
  • Large community of around 5M developers
  • Built on AngularJS and Apache Cordova
  • Widely used for both native and progressive web apps

Additionally, it is notable that Ionic utilizes front-end technologies such as CSS, HTML, and JavaScript.

In Conclusion

Cross-platform app development provides a great advantage in the mobile app market for SMEs, startups, and other large enterprises. A major part of the mobile app market is shared by Android and iOS, so almost every leading cross platform framework emphasizes on advancements towards them.

To choose the best cross-platform app framework, you can refer to the list provided above. With right technology in your favor, you can come up with the best approach for business growth.
