ComfortCast

ComfortCast helps you understand how comfortable today's weather will feel for exercise and outdoor training. Before you run, play, train, or head to the court, ComfortCast combines live weather data with temperature and dew point, wind, UV, air quality, weather alerts, and environmental exposure. It turns those conditions into a clear Comfort Score, risk level, reasons, and practical suggestions. With approximate current location enabled, you can review exercise comfort across the next 24 hours and seven days and see each day's suggested activity time. After an activity, record whether the weather felt comfortable, warm, or difficult. ComfortCast gradually calibrates future scores to your experience. Save frequent activity routines and use home screen or lock screen widgets to check the latest score at a glance. The current release supports tennis, running, several indoor and outdoor environments, English, Simplified Chinese, and Traditional Chinese, plus Celsius or Fahrenheit units. More activity types will follow. Weather data is provided by QWeather. QWeather credentials stay on the ComfortCast backend and are not included in the iOS app.
