I created an app (for mobile devices) and it's 100% HTML5 and JS. I didn't use anything like Java or another native coding language. Of course I can put the app on the internet and access them like a website. But I want to get the app exported as a download, like it's an app you get from the playstore. It must be downloadable because it should be usable without an internet connection.
I created the app by just typing the HTML and javascript files. Should I zip them together, or put them in one folder, and just download it on the device? And then create a webpage where the app can be downloaded?
