HeatOK: Heat Index & WBGT

HeatOK helps you understand hot, humid weather before you head outside. See the current Heat Index, Wet-Bulb Temperature (WBT), and Estimated Wet-Bulb Globe Temperature (WBGT), then plan around the lower-risk hours in your day. With HeatOK, you can: • Use Heat Index, Estimated WBGT, or air temperature as your primary scale. • See Wet-Bulb Temperature, globe temperature, humidity, dew point, wind, and UV Index together. • Follow the hourly heat path and check the day ahead. • Choose an outdoor context for relevant precautions, including exercise, outdoor work, caregiving, and dog walks. • Check heat risk, Heat Index, WBGT, and the hourly forecast on Apple Watch (companion to the iPhone app). • Ask Siri or run a Shortcut for the current heat risk, temperature, WBGT, or the best outdoor window. • Save places, use Home Screen widgets, and set personal threshold alerts. Some features require HeatOK Pro. Every reading identifies its scale, source, and data freshness. Estimated WBGT is calculated from forecast weather data and does not replace an on-site globe thermometer. HeatOK provides weather information and general precautions. It is not medical advice or an emergency service.
