AppFramework is a library for the quick and easy creation of your own app in just 80 lines of code, simultaneously as a native application for Android and IOS. The AppFramework communicates with its own reference server to display the content. The content required for this is synchronized between your own app and the reference server using an API. It is possible to design your own app without any knowledge of app programming. Knowledge of web design languages (XAML and/or HTML, CSS, JAVASCRIPT, REACT, ANGULAR, etc.) is sufficient for the presentation. Native functions such as camera access, barcode reading, GPS, calendar notifications are provided by the framework. The AppFramework includes a demo app that makes it easy to get started with the project. This allows the possibilities of the AppFramework to be demonstrated.
