📱 Mobile Features

Haptic Feedback System

The app features an advanced haptic feedback system with:

• 30+ Weather-Specific Patterns: Unique vibrations for different weather conditions
• Contextual Intelligence: Intensity varies by temperature, time of day, and weather severity
• Progressive Feedback: Multi-stage haptics for complex interactions
• Battery Optimization: Smart triggering with rate limiting and intensity scaling

Weather Haptic Patterns

// Clear weather - gentle pulse
clear: [15, 60, 15];

// Rain - rhythmic droplet simulation
rainy: [30, 20, 30, 20, 30];

// Thunderstorm - powerful strike pattern
thunderstorm: [80, 40, 60];

// Wind - gusting wind simulation
windy: [20, 40, 30, 60, 40];

Location Services

• Automatic Detection: GPS-based location with fallback to IP geolocation
• Smart Caching: Intelligent storage with automatic cleanup
• Background Updates: Periodic location refresh with battery awareness
• Network Optimization: Adaptive behavior based on connection quality

Swipe Navigation

• Bi-directional Swiping: Navigate between Home and Weather screens
• Visual Feedback: Progress indicators and smooth animations
• Haptic Integration: Touch feedback during swipe interactions
• Gesture Recognition: Velocity-based swipe detection with thresholds
