Chickaree icons for Windows 10 are designed to match the original icons of Windows 10; we’ve summarized this design system in our article that Microsoft has failed to produce. Optimized for 32×32 pixels, these are our cleanest outline icons, only to compete with our small 1em icons and way less detailed as our iOS icons. Like all our free icon packs, these Chickaree icons are available for download as PNG, SVG, PDF and other vectors, as an icon font, and as HTML/CSS snippets.
These are the Chickaree icons for iOS. They follow the iOS Human Interface Guidelines (Apple could have done it better though), first introduced in iOS 7 and supported in all later releases up until now (at least iOS 11). These are outline icons; they're based on thin two-pixel lines and is optimized for 50×50 pixels. If you're creating an iOS app, either download Chickaree PNG icons in 3 sizes (free icons for 50 and 100px; for folks who paid there's 150px) or download a single vector icon in PDF format (you'll have to buy icons) — Xcode will generate the proper PNGs on the compilation. There's a matching set of glyph icons — Apple introduced them in iOS 11 and uses for tab bars.
