Represent the App Type with the Icon Concept as one bold, centered symbol inside a single rounded-square iOS-style app icon. Use the Icon Style and Color Palette to create a simple soft 3D treatment with gentle shading, restrained highlights and believable material, while keeping the key tag silhouette crisp and instantly readable. Make the crescent moon a clean negative-space cutout with comfortable padding and strong contrast against the icon background. Use a solid or subtly graduated icon background, with no text, letters or extra objects inside the icon. Present the icon alone, centered on a plain very light neutral background, occupying about 70 percent of the square 1:1 canvas. Add a soft, subtle drop shadow beneath the icon. The result should look like a finished App Store or Google Play icon from a top Dribbble or Behance presentation: clean edges, balanced geometry and no device, hands, mockup, watermark, glow, sparkles or detailed scene.
Use these details:
App Type: "Hotel booking app"
