Convert website to App and IOS

Convert website to App and IOS

I have website already and my website is friendly with mobile preview very well.
What I want, I need to convert my whole website to app and iOS without rebuilding the whole thing. I just want to put my Website URL, icon or custom logo and then we can convert our website to app and IOS. 
I want to Convert website link into mobile app, is there possible like that?
