App icons

Design a single app icon for a fictional app and present it as a finished, high-fidelity asset. Treat the icon as a tiny composition: one symbol, one shape system, and a tight color palette. No UI screens, no branding page, no text inside the icon.

Build for the constraints of a home screen. The icon should hold its form at small sizes, work inside common rounded-square masks, and stay legible against both light and dark wallpapers. Use simple geometry, controlled contrast, and enough negative space that the mark does not collapse when scaled down.

Show the icon in context on a device home screen so its silhouette, color, and distinctiveness can be judged against neighboring apps. Include a light-background version and a dark-background version if the design depends on background treatment. Keep the presentation focused on the icon itself, not on marketing copy or feature explanation.

Keep scale in mind—your icon should be distinguishable and look equally good at larger sizes for app stores, and smaller sizes for devices.
