Based om my experience with android but surely any mainstream smartphone works a bit like this.

That isn’t up to the website necessarily. Every app states what links it supports to your phone, that will open the appropriate app automatically. On android you can change this behaviour on a per link per app basis in settings>apps>app-name>"open by default"

With one of the backups off-site!
