Design one single mobile app icon for the App Type, using the Icon Concept as one bold, centered symbol with comfortable padding. Render it as a clean iOS-style rounded-square icon with smooth squircle corners, filling the shape with the Color Palette. Follow the Icon Style with crisp solid shapes, a strong silhouette, smart negative space and no unnecessary detail. Make the tuning needle clearly readable across the guitar pick at small sizes, with strong contrast between the symbol and its background. Present the icon centered on a plain very light neutral background, taking up about 70 percent of the square 1:1 canvas, with a soft subtle drop shadow beneath it. Show exactly one icon, with no device, hands, mockup, text outside the icon, extra objects, thin lines, glow, sparkles, photographic texture, watermark or resemblance to an existing app icon, brand logo or mascot.
Use these details:
App Type: "Guitar tuner"
Icon Concept: "A guitar pick with a tuning needle crossing it"
Icon Style: "Flat illustration"
Color Palette: "Amber and black"
