Install next cloud dashboard from browser

Hi all,
I bought a Nextcloud package to have calendar and contacts management. If I go to the website for the first time from a browser on Android, clicking on the three dots of the browser I get (among the usual choices such as history, download, add to Home Screen, etc) the choice to “Install app” and actually the Nextcloud dashboard is installed and then from that moment on I can go to the website through the app rather than through the browser (it’s much better). Unfortunately, I can’t do the same from Iphone because on the browser Indonr get the “Install app” choice. Do you know the reason why this happens ? Is there anything to do to get the app on iPhone so that I can access the website from the app ? Thanks

You can also just install the app from the app store. It’s called Nextcloud.
