This is a single 3D style app icon featuring a rounded square shape in bright blue with a purple lightning bolt symbol at its center. A lighter blue cylindrical element extends from the right side, creating depth and a playful, modern look. The soft shadows and pastel color mood make it ideal for mobile app branding, onboarding screens, or hero sections in Figma, Framer, or Webflow.
