I've found that new SF UI font for download (http://nomail.com.ua/font/SF%20UI%20Display). I wonder if it's legal to use it in the web app I am building now, i.e. for commercial use? I haven't found any licence info on the official page (https://developer.apple.com/fonts/).
This question generally answers the question of legality.
Including these font files in your app and using them with @font-face
or @import
is unquestionably not permitted.
However, for a web app you can non-explicitly use it by specifying special keywords in your CSS:
body {
font-family: system-ui, -apple-system, BlinkMacSystemFont, "Helvetica Neue",
"Lucida Grande", "Segoe UI";
}
This will, of course, result in slightly different appearances per platform and version (namely non-Apple platforms and Apple systems before iOS 9/OS X 10.11).

Nowadays,
system
should probably be replaced withsystem-ui
. See: drafts.csswg.org/css-fonts-4/#system-ui and chromestatus.com/feature/5640395337760768 – Dem Pilafian Nov 12 '17 at 2:52 -
