Sweat Score turns complex weather into a simple, glanceable 0–10 scale that shows how hot it will feel—hour by hour—so you can pick the best time to get outside. Whether you’re running, walking, commuting, or planning a workout, Sweat Score blends temperature, humidity, sun angle, wind, cloud cover, and rain chance into one clear number. Swipe through the next 24 hours, see the story behind the score, and choose the most comfortable window for your plans. Why Sweat Score? Traditional weather apps tell you temperature. Sweat Score tells you how it will actually feel for your body, especially during activity. It factors in: • Temperature and humidity (humidex-style heat stress) • Sun altitude and cloud cover (direct sun vs. shade) • Wind speed (cooling effect, reduced when humidity is high) • Rain chance (visualized at a glance) Key Features • Hourly 0–10 Sweat Score: A single rating that reflects real‑world comfort and heat strain. • 24‑Hour Forecast: Swipe across the day to find your ideal time to get outside. • Dynamic Background: Color shifts with the Sweat Score, with a subtle blue band indicating rain chance. • Quick Metric Tooltips: Tap icons to see what each number means (temperature, humidity, rain, cloud cover, wind, sun). • Location‑Aware: Automatically detects your location and formats units to match your region (°C/°F, km/h/mph). • Clear Labels: “Low,” “Medium,” “High,” and “Extreme” make the score easy to interpret at a glance. • Smart Refresh: Returns to the current hour and updates data when you come back after a while. How It Works Sweat Score uses Apple’s WeatherKit for high‑quality forecasts and sun position data to estimate heat load. The algorithm: • Increases the score with higher temperature, humidity, and stronger sun. • Reduces the score with wind cooling (less effective in high humidity). • Shapes results into a 0–10 scale so you can compare hours quickly. This isn’t just a “feels like” temperature—it’s a practical, activity‑minded indicator for planning. When to Use It • Scheduling runs, rides, or walks for the least sweaty time of day • Avoiding mid‑day heat and direct sun exposure • Picking comfortable windows for outdoor chores or commutes • Deciding between morning, afternoon, or evening outings Privacy & Transparency • Your location is used on device to fetch a local forecast. • No unnecessary data collection. Your data stays yours. Plan smarter. Sweat less.
