Design one single mobile app icon for the App Type, presented exactly like a real App Store or Google Play icon. Use the Icon Concept as one bold, simple symbol centered inside a rounded-square iOS squircle with smooth corners and comfortable padding. Apply the Icon Style with crisp edges, clean solid shapes, a strong silhouette and smart negative space so the symbol remains instantly readable at small sizes. Use the Color Palette with strong contrast between the symbol and the icon background. Center the icon on a plain very light neutral background, sized to about 70 percent of the square 1:1 canvas width, with a soft subtle drop shadow beneath it. Show no device, hands, mockup, extra objects or text outside the icon. Avoid detailed scenes, thin lines, tiny details, glow, sparkles, photographic textures, watermarks, random lettering and resemblance to existing app icons or logos.
Use these details:
App Type: "HR app"
Icon Concept: "Briefcase with a heart-shaped clasp"
Icon Style: "Flat icon design"
Color Palette: "Plum and peach"
