Design a single mobile app icon for the App Type, using the Icon Concept as one bold, instantly readable symbol. Present it as a real App Store or Google Play icon: an iOS-style rounded-square shape centered on a plain very light neutral background, occupying about 70 percent of the square 1:1 canvas, with a soft subtle shadow beneath it. Apply the Icon Style with clean solid shapes, crisp edges, comfortable padding and smart negative space. Use the Color Palette with strong contrast between the symbol and the icon background. Keep the form simple and iconographic rather than a detailed scene or illustration. The result should feel original, friendly and clear at small sizes. Show no device, hands, mockup, text outside the icon, extra objects, thin lines, tiny details, sparkles, glow, lens flares, photographic texture, watermarks or resemblance to an existing app icon, logo or mascot.
Use these details:
App Type: "Baby names app"
Icon Concept: "A baby rattle shaped like a speech bubble"
Icon Style: "Flat illustration"
Color Palette: "Soft yellow, warm cream and muted charcoal"
Using your own logo, product or face? Attach it in the chat and say which of the details it replaces.
Your result will come out close to the example rather than identical to it. Change the details to make it yours.
