Present the App Type as one single mobile app icon, centered on a square 1:1 canvas. Use a smooth iOS-style rounded-square shape with the Icon Style, applying the Color Palette as a solid background or very subtle two-tone gradient. Translate the Icon Concept into one bold, clever symbol with a strong silhouette, crisp edges, comfortable padding and an instantly readable form at small sizes. Keep the symbol simple and iconographic rather than a detailed scene or illustration. Use strong contrast between the symbol and its background. Place the icon at roughly 70 percent of the canvas width on a plain very light neutral background, with a soft, subtle drop shadow beneath it. Show exactly one icon with no device, hands, mockup or text outside the icon. Do not add lettering, tiny details, thin hairlines, sparkles, glow, lens flares, photographic textures, watermarks or resemblance to existing app icons, logos or mascots.
Use these details:
App Type: "Alarm clock app"
Icon Concept: "Twin-bell alarm clock with sleepy eyes"
Icon Style: "Flat illustration"
Color Palette: "Mint green, deep charcoal and off-white"
