IonWordpress is a high quality mobile app template built with Ionic Framework, which grabs your WordPress site content and puts it inside an app. You will need to be able to add some plugins to your WordPress site and to know how to build an Ionic app. Then you will have a mobile app ready to go. It has tons of components, plugins and examples so you can build the kind of app you need.
The app uses SASS, which basically is CSS with super powers. Each component has its dedicated sass files and partials well structured with independent variables so you can have maximum modularity, flexibility and customizability.
