There is a site. There is a Smartphone (Windows Phone). We have to transfer. What do you need to know?

Question

PHP

There is a site - dotapicker.com
If you open it on a smartphone, it loses all its functionality.
The goal is to make an application on a smartphone based on this site.
There are several options:
Either create an application through WAT (Web App Template)
Or create a separate program with the same principle as on the site.
Of course, the WAT option is simpler, but if you pay attention to the second option, what knowledge do I need to develop such a program for WP (Windows Phone)?
If you were writing such a program in C#, what sections, templates, plug-ins, books would you advise to pay attention to? (Specifically for such a program).

Answer 1

/*сайт на пыхе вообще...
какой понт тебе от этой программы?*/

I think it's pointless
