Any one please explain about the app maker

Question

I am totally confused

Answer 1

If you're referring to this app maker - https://developers.google.com/appmaker/ - it seems to be a program developed by Google that uses a drag-and-drop UI and JavaScript to create various types of applications. I haven't exactly used it myself for creating anything, but if you want to learn about how to use it, the website seems to have quite a few good tutorials to get you started.
