Installing on a phone
Adding Kardamone to your home screen, with the steps for your phone and browser.
Kardamone works in a phone's browser with nothing installed. Installing adds an icon to the home screen and opens the site full-screen, without the address bar — and that is what makes offline use comfortable.
The steps, in pictures
The install page asks you two things — which phone, which browser — then shows the matching steps, with a picture for each. It also has a QR code: scan it with the phone to open Kardamone there directly.
The QR code holds the site's address and nothing else. It does not sign you in and holds no password: after installing, sign in once on the phone.
Two impossible pairs
Safari does not exist on Android: use Chrome or Firefox. And Firefox on iPhone cannot add a site to the home screen: open the address in Safari and follow its steps. The page says so too, rather than showing nothing.
