Build a professionally made App Store screenshot for the App Name, formatted as one vertical 9:16 image. Place the Headline at the top in large, bold, clean sans serif type, exactly as written and within two lines. Add the Subline beneath it in smaller, legible type. Use the Background across the full canvas and apply the Brand Color consistently to the interface and accents. Below the text, show a generic modern smartphone with thin bezels, no brand logo, and the Device Angle. Give it a soft realistic shadow and comfortable margins from every edge.
Place the App Screenshots inside the phone screen exactly as provided when supplied. Otherwise, design a believable dark-mode sleep tracking interface based on the Screen Content, with sensible labels, clean components, legible text, and a status bar showing 9:41. Use the App Icon exactly when supplied. Keep the phone screen sharp and readable. Render accurate spelling, realistic UI spacing, and a calm nighttime composition. Avoid star ratings, reviews, award laurels, download counts, store badges, glow, sparkles, lens flares, glass effects, busy backgrounds, watermarks, and any platform logos.
