Stay informed and protected with the WBGT Estimator app—your reliable companion for monitoring heat stress conditions and planning safely in hot environments. The app provides real-time Wet Bulb Globe Temperature (WBGT) estimates alongside a detailed 36-hour forecast, helping you anticipate and respond to changing conditions. Whether you’re using automatic location or entering a ZIP/postal code manually, WBGT Estimator taps directly into Apple WeatherKit to pull hyper-local data, including temperature, humidity, wind speed, cloud cover, and UV index. You can even switch to “Feels Like” mode for an alternative view of heat stress that better reflects human comfort levels. The calculation is fully customizable—users can toggle the influence of wind, UV, and cloud cover to tailor readings to their specific needs or policies. The clean interface features color-coded flag conditions with easy-to-understand safety guidance tailored to work, exercise, or outdoor leisure. Scroll through the hourly forecast to monitor how conditions evolve, tap any flag condition to update automatically, and rely on the built-in location display to confirm where the data applies. When it’s time to share, built-in options let you send daily WBGT summaries via email, text, or copy them to your clipboard for flexible use across platforms. A quick-access external link also connects you to additional resources on WBGT, flag meanings, and heat safety practices. WBGT Estimator empowers you to make smart decisions under the sun. It’s not a substitute for judgment—but it puts the right information at your fingertips when it matters most. ## Key features - Real-time WBGT estimates - 36-hour WBGT forecast - Hyper-local weather data integration - Customizable WBGT calculations - Color-coded safety guidance - Shareable WBGT summaries ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/wbgt-estimator/id6739461541/reviews.md ### 4/5 — Solid start *2025-07-19* Simple, quick and effective forecasts. It’d be nice to have the flag scales as a reference and support metric measurements, though. **Developer response:** I have been considering adding an additional function for the user to establish what they want the WBGT ranges to be…give flexibility. As it stands, the flag conditions are as follows: WBGT 79.9 and Below - No Flag WBGT 80 to 84.9 - Green Flag WBGT 85 to 87.4 - Yellow Flag WBGT 87.5 to 89.9 - Red Flag WBGT 90 and Greater - Black Flag Thank you for your feedback!
