Sky-Sense — Weather Forecasting App
Sky-Sense is a hyperlocal weather experience that transforms its entire visual identity based on real-time conditions. Eight complete visual themes respond to the weather — sunny days get warm golden gradients and floating light particles, rainy evenings get deep blues and animated falling raindrops, stormy nights get dark purples and dramatic rainfall, clear nights get deep navy with twinkling stars. Every theme has its own colour palette, glassmorphism card styling, and canvas-rendered particle animation. When conditions change, Framer Motion cross-fades the entire interface in under a second. Beyond the visuals, the app surfaces genuinely useful information. A suggestion engine evaluates the combination of temperature, weather code, UV index, and wind speed to generate outfit recommendations and activity advice — telling users not just what the weather is, but what to do about it. Air quality data shows AQI alongside individual pollutant readings (PM2.5, PM10, NO₂, ozone) with plain-language health advice. A 24-hour scrollable hourly timeline and 7-day daily forecast complete the picture
