San Francisco is a typeface developed by Apple Inc. as the system font for its operating systems, including macOS, iOS, and watchOS. It was first introduced in 2014 for use on the Apple Watch, and later expanded to other devices.
San Francisco is a modern, minimalist font that is designed for legibility across a range of screen sizes and resolutions. It contains both serif and sans-serif variations, as well as different weights, allowing for a wide range of design possibilities.
The font also includes a number of unique features, such as adaptive kerning, which adjusts the spacing between letters based on the specific combination of characters, and a dynamic tracking feature, which adjusts the spacing between all letters based on the overall width of the text block.
Overall, San Francisco is a versatile and functional font that has become an integral part of the Apple user experience.
