If you manage outdoor activities in hot conditions, this app takes the guesswork out of heat safety. It provides precise Wet Bulb Globe Temperature readings along with activity guidelines based on recognized scales. A must-have for anyone responsible for athlete or worker safety in high-heat environments.

My Full Experience

I've been testing Zelus WBGT with our high school athletic program, and it's become an essential part of our safety protocol. The app delivers exactly what it promises: accurate WBGT readings that help us make informed decisions about practice modifications. Unlike some weather apps that confuse wet bulb temperature with WBGT, this one gets it right - which matters when you're deciding whether to cancel soccer practice or shorten football drills. What stands out is how it translates complex meteorological data into actionable recommendations. The color-coded risk scales (from green to black) immediately show whether conditions are safe, require caution, or warrant canceling activities. I compared readings against our school's handheld meter and found them consistently within 1-2 degrees, which is more than accurate enough for safety purposes. The interface is straightforward without unnecessary fluff - you get current conditions, hourly forecasts, and clear activity guidelines. My only minor gripe is that the location detection sometimes needs manual adjustment when you're between weather stations, but that's fairly common with hyperlocal weather apps. For coaches, construction supervisors, or anyone managing outdoor teams, this $3.99 app could literally prevent heat-related illnesses.

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.
