looks like this website is counting the wrong thing.
EG My user agent is "Mozilla/5.0 (iPhone; CPU iPhone OS 18_7 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/26.1 Mobile/15E148 Safari/604.1"
is probably getting counted as iphone 18.7 but I am running 26.1, which is also reported in the user agent.
