We designed and developed an open-source environment custom-made for the professional community that empowers them to build apps for everyone quickly and conveniently. We utilize Open Source so we have the ability to respond to any demand immediately. King of App is the referee in the community that ensures code quality while nurturing a community of resources that allows for unlimited growth. Our philosophy is simple: easy to learn software. With that goal in mind, we decided to go with widely known web technologies to ensure access to other technologies while setting the standards in mobile app creation. We are not happy in just assisting the content distribution process and the app development. We are going one step further by allowing anyone to have access to thousands of tools to create an optimal customer engagement through their app. To be able to deliver quality code, we are bidding for a modular system that allows us to prepare templates with modules under an open source umbrella. This allows us to connect any data source and to customize the app with free code access. Finally, King of App offers services, granting universal access to engage authors and users, creating a communicative ecosystem in both directions.
