What are the names of mobile applications that load the mobile version of the site?

Question

Mobile development

I have 2 questions on this topic.
1) What is it called when, in fact, there is an application in the markets, but when you download it, it turns out that it loads the mobile site in your native browser, while you do not see the URL and so on. In most cases, it looks like an application.
2) With what help is it implemented?

Answer 1

2) html5 + css3 + cordova
