There are websites out there that will seamlessly convert a website into a mobile application. One such site is Median (formerly known as GoNative).

Using Median, all one has to do is provide their URL, wait briefly for the site to create the application, and download the app. However, Median allows for plenty of customization from modifying the launch screen, changing prominent colors, disabling/enabling features like zooming in/out by pinching fingers, etc. Many customization options are free, however some may require payment, such as adding advertisements or push notifications. Regardless, it completely doable to create a fully functioning mobile application with Median.
