SF Symbols is Apple's own symbol library and companion Mac app: over 7,000 symbols in 9 weights and 3 scales, built to align with the San Francisco system font and Apple's platforms.
Symbols that auto-align with SF Pro text and adapt to reading direction and 20+ international scripts solve typography-matching problems a generic icon set can't, since Apple designed both together.
The right choice specifically for native iOS, iPadOS, macOS, watchOS, tvOS, or visionOS apps: it isn't intended for general web use.
Free, but the browsing/export app requires macOS Sonoma or later and use is scoped to apps built for Apple's platforms per Apple's guidelines; it also supports multi-layer symbols for custom animation (Draw On/Off, variable rendering for progress indicators).
