Due to the plethora of mobile platforms available, a mobile app development company faces quite a bit of problem when asked to create an application that can be used on all platforms. However, there are development tools available that allow the creation of mobile apps that can be installed and used in various platforms. These cross platform frameworks allow developers to build a single code for the app which can be easily modified to suit different mobile platforms.
Angular.js is more commonly known as Angular. It is a framework for developing web based applications and is open-source. It is maintained by not only Google, but also a community of mobile app development companies and individual developers. Angular.js allows developers to combat the various problems that can be faced when a single-page application is being developed. The primary aim of this framework is to simplify the development of the apps as well as make their testing an easier process.
The Iconic Framework is open source and it is used to develop mobile web applications that are based on HTML5. The Ionic Framework is focused on the front-end of the applications which is the one which the users see. In other words, the Ionic Framework is used for developing and improving the UX or User Experience of the app. The framework concentrates on the user interface and is used for making improvements to the intuitive operation of the app and also to make the usability simpler. The Ionic Framework is most commonly used alongside Angular.js. While Angular.js is used to build the structure of the app, the Ionic Framework is used to improve the look as well as the feel of the app. The latter is also used for improving the performance of the app.

In order to create applications that can be used on a variety of mobile platforms, it is inessential that those applications are coded and built using cross-platform platforms and scripting languages. The above mentioned tools are all cross platform compatible.
