Design one single mobile app icon for the App Type, using the Icon Concept as a clever, instantly readable symbol. Follow the Style with a strong silhouette, crisp edges, comfortable padding and smart negative space so the design remains clear at small sizes. Use the Color Palette with strong contrast between the icon background and symbol. Present it as a real App Store or Google Play icon: a rounded-square iOS squircle centered on a plain very light neutral background, occupying about 70 percent of the square 1:1 canvas width, with a soft subtle drop shadow beneath it. Keep the interior simple, bold and iconographic rather than illustrative. Show no device, hands, mockup, extra objects, multiple icons, variants, text outside the icon, thin lines, tiny details, glow, sparkles, lens flares, photographic texture, watermarks or recognizable existing logos.
Use these details:
App Type: "Online courses app"
Icon Concept: "A graduation cap resting on a play button"
Style: "Flat bold"
Color Palette: "Red and black"
