+# LifeTimer - App Icon Guidelines
+
+## Icon Design Specifications
+
+### Concept
+The LifeTimer app icon should represent:
+- Time/countdown theme
+- Progress and achievement
+- Motivation and forward movement
+- Clean, modern aesthetic
+
+### Design Elements
+
+#### Primary Elements
+- **Hourglass or Timer**: Central element representing time
+- **Progress Ring**: Circular indicator showing completion
+- **Arrow/Upward Motion**: Symbolizing progress and achievement
+- **Number 1356**: Subtle reference to the challenge duration
+
+#### Color Palette
+- **Primary**: #6366F1 (Indigo) - Main brand color
+- **Secondary**: #8B5CF6 (Purple) - Accent
+- **Highlight**: #EC4899 (Pink) - Energy and motivation
+- **Background**: Gradient from primary to secondary
+
+#### Style Guidelines
+- **Flat Design**: Modern, clean aesthetic
+- **Minimalist**: Simple shapes, clear focal point
+- **Scalable**: Must work at all sizes (from 16x16 to 1024x1024)
+- **High Contrast**: Ensure visibility on all backgrounds
+- **No Text**: Avoid text in the icon (except possibly "1356" as a subtle element)
