Present one App Type icon as a real App Store or Google Play app icon: a rounded-square iOS squircle centered on a square 1:1 canvas, occupying about 70 percent of the width. Use the Color Palette with strong contrast, and render the Icon Concept as one bold, centered symbol with comfortable padding, a clear silhouette, crisp edges and smart negative space. Follow the Style with clean solid shapes and no unnecessary detail. Keep the background plain, very light neutral off-white or light gray, with a soft subtle shadow beneath the icon. Make the result instantly readable at small sizes and refined enough for a top Dribbble or Behance icon presentation. Show no device, hands, mockup, extra objects, text outside the icon, tiny details, thin lines, glow, sparkle, lens flare, watermark or branding.
Use these details:
App Type: "Currency converter"
Icon Concept: "Two coins swapping places around a circular arrow"
Style: "Flat icon design"
Color Palette: "Gold and emerald green"
