Answer 1

Since Chrome 42 there is now a standard way of accomplishing this that prompts the user to add your application to the home screen as long as your web application fulfills the following requirements:

• You have a web app manifest file
  • The manifest defines how your app appears on the user’s system and how it should be launched - and you are required to have a short_name and a 144x144 png icon
  • Your icon declarations should include a mime type of image/png
• You have a service worker registered on your site. We recommend a simple custom offline page service worker
• Your site is served over HTTPS (you need a service worker after all)
• The user has visited your site twice over two separate days during the course of two weeks.
