Is there a list of supported fonts for Safari Mobile (ie. iPad and iPhone)?

I'm looking for an exhaustive list of the supported fonts in Safari Mobile for iPad and iPhone. In fact, which fonts can I use in my website?

What font does Safari use on iPhone?

The default Safari font is now Helvetica Extra Light.

San Francisco is the default font for iPhone and iPad.

How do I change font in Safari on iPad?

To get started, open the Safari browser on your iPhone or iPad and visit the web page where you want to increase or decrease the text size. Next, tap the “aA” button on the left-hand side of the URL bar. Here, tap the “a” button to reduce the text size, or tap the “A” button to increase the text size.

You should try this site: http://iosfonts.com/

it has a table with all supported Fonts for iPhone and iPad
