Zelus WBGT provides real-time environmental monitoring for organizations managing outdoor safety risks. The app delivers WBGT readings, lightning detection, and air quality data without requiring hardware, serving sports teams and industrial operations.

Detailed Review

Zelus WBGT represents a sophisticated approach to environmental risk management, offering organizations a hardware-free solution for monitoring potentially dangerous outdoor conditions. The application positions itself as an enterprise-grade tool trusted by military organizations, Fortune 500 companies, and athletic programs seeking to maintain operational safety compliance. The core functionality centers on Wet Bulb Globe Temperature (WBGT) monitoring, which combines temperature, humidity, wind speed, and solar radiation into a single heat stress metric. Additional features include real-time lightning detection within a user-defined radius and Air Quality Index (AQI) readings. The platform provides customizable alert thresholds and activity recommendations based on established safety scales, enabling organizations to implement standardized safety protocols across multiple locations. User experience demonstrates a professional interface designed for quick access to critical data. The dashboard presents current conditions with color-coded risk indicators, while historical data tracking allows safety managers to analyze trends and demonstrate compliance. Real-world usage patterns show organizations deploying the app across athletic fields, construction sites, and military training facilities where environmental conditions directly impact operational decisions and personnel safety. User feedback consistently praises the accuracy and convenience compared to traditional handheld meters. Reviewer merikus1 (2023-07-15) noted the app 'does exactly as advertised' in providing clear WBGT readings with activity recommendations. ComoSteve (2022-08-05) verified accuracy against physical meters, finding readings 'identical or very close.' Multiple reviewers from educational and athletic backgrounds describe the app as integral to their safety protocols, though the 3.68 rating suggests some users may encounter interface or data accuracy concerns not reflected in the sampled reviews. The application excels in providing professional-grade environmental monitoring without hardware investment, though its utility depends heavily on reliable weather data sources. Organizations requiring precise, location-specific measurements may still prefer physical meters for mission-critical applications. Ideal use cases include school athletic programs, construction safety managers, and military units needing portable environmental assessment capabilities across multiple locations.

This app is a great example of a tool that does exactly as advertised. Do you want to know the WBGT? This will give it to you. It will also allow you to see various scales for WGBT and their recommendations for outdoor activities. As opposed to other apps, it’s clear you’re getting the WBGT here and not the Wet Bulb Temperature, which are (unfortunately) two different things. And that’s enough. If you need the WBGT and know what that is, then this is the app for you. If you don’t, go google it and then come back and download this app. WBGT is quite useful, and this app usefully provides it.

I started using the app recently and it is a lot more convenient than carrying around a handheld. I checked the readings against a handheld and they are either identical or very close. So far, so good. Quicker and more convenient than a handheld meter I started using the app recently and it is a lot more convenient than carrying around a handheld.

Works just fine for me and shows the Wet Bulb Global Temperature where I live in Massachusetts. If you are unaware WBGT is not how we normally measure temperature. It will look completely different than your normal forecasts and is useful for knowing how safe it is to exercise outdoors in your area. I really didn’t like how I had to make an account. The app already asks for your location so there is no need for it to save other data just to deliver local weather. The built in weather app doesn’t need an account, this one shouldn’t either Decent app. Requires making free account Works just fine for me and shows the Wet Bulb Global Temperature where I live in Massachusetts.
