Navigate in a site being able to go back.

Hi everyone.
I am completely ignorant in this matter.
I wanted to ask if any of you can help me step by step to create an app.
I tried to view my website in the app.
It works fine, but unfortunately there is no "go back" button
if I try to go back with the "button" of the phone "the application closes.
I just want you to be able to browse my site using the app. But unfortunately it is only possible one way.
Who can help me solve this problem?
Thanks
