Design one single mobile app icon for the App Type, using the Icon Concept as the central symbol. Present it as a true App Store or Google Play icon: a rounded-square iOS squircle with smooth corners, 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. Use the Style and Color Palette with strong contrast between the icon background and symbol. Keep the symbol bold, simple and instantly readable at small sizes, with comfortable padding, a strong silhouette, crisp edges and clever negative space. Use only a few clean shapes and no detailed scene or illustration. The result should feel original and thoughtfully designed, like a top Dribbble or Behance icon shot. Show no device, hands, mockup, extra objects, text outside the icon, watermarks, sparkles, glow, lens flares, photographic texture or resemblance to an existing app icon, brand logo or famous mascot.
Use these details:
App Type: "Swimming app"
Icon Concept: "Swim cap with goggles"
