Translate the App Type through the Icon Concept as one bold, instantly readable symbol. Present a single rounded-square mobile app icon with smooth iOS-style squircle corners, centered on a plain very light neutral background and occupying about 70 percent of the square canvas. Use the Style with crisp edges, strong silhouette, comfortable padding and smart negative space. Fill the icon with the Color Palette, keeping strong contrast between the background and the face. Center the face and divide it vertically: one side has a clear, friendly smile and the other has a calm neutral mouth, with matching simple eyes. Keep the design flat, minimal and original, with no detailed scene, extra objects, thin lines, glow, sparkles or texture. Add a soft subtle shadow beneath the icon. Square 1:1 composition, no device, hands, mockup, watermark or text outside the icon.
