Hello, 

Thank you in advance for your time and quick reply

I need an app for my e-shop, I just need to any user be able to install my app on their mobile device, no matter OS (Android or IOS) and then can see my website as it looks. 

Thank you very much

My website is: smobile-energy.com

You can check my website in order to see my web is able to see it in any device no matter the screen size.
