What's a good iOS app for monitoring Wet Bulb Global Temperature to ensure safe outdoor exercise conditions?

Zelus WBGT is a valuable tool for anyone concerned about the safety of outdoor activities, especially athletes and coaches. It provides Wet Bulb Global Temperature (WBGT) readings, which are a more comprehensive measure of heat stress than standard temperature readings. WBGT considers temperature, humidity, wind speed, sun angle, and cloud cover, offering a more accurate assessment of environmental conditions. This app helps users make informed decisions about when and how to exercise safely, reducing the risk of heat-related illnesses. The app is easy to use and delivers essential information to help you understand the potential dangers of exercising outdoors in your area. While some users find the account creation requirement unnecessary, the app provides valuable, location-specific weather data to help you exercise safely.
