The First of Its Kind App Designed to Accurately Give Wet Bulb Globe Temperature Readings in Seconds.

Keep track of the Wet Bulb Globe Temperature (WBGT) on some of the hottest days of the year to protect yourself from heat-related conditions, such as heat stroke, exhaustion, cramps, and heat rash.

Zelus goes beyond traditional WBGT readings by combining details of hyperlocal weather data, such as the relative humidity, solar radiation, angle of the sun, cloud cover, air temperature, and more, to provide the most valuable and accurate information. Receive precise data with the press of a button from anywhere.

Free Features:

• WBGT reading – WBGT reading at your current position.
• Current Hyperlocal Weather Data – Numerous current weather data points at the device’s location.

Paid Features:

• WBGT Anywhere in the World – Obtain WBGT readings anywhere in the world.
• Regular Temperature Threshold Alerts - Get instant alerts when the WBGT exceeds your threshold.
• Save Your Data in Seconds - Choose to save your readings with the press of a button.
• Automated Documentation – Carrying paperwork with you is no longer needed. Export your saved data to your email in seconds.
• Hassle Free – No more looking for batteries. No more calibration. No more running back to the office for a forgotten device.
• No Equilibration Needed - Get the valuable details you need in less time. The Zelus app doesn't require equilibration, so you can get temperature readings in mere seconds instead of waiting 15 minutes or more.

Stay safe when out in the sun on some of the hottest days by periodically checking the Wet Bulb Globe Temperature in the area. It's as simple as pulling out your phone, opening the app, and allowing its complex mathematical algorithms to do the work for you, providing you with the instant results you want and need.

Whether you're playing football, soccer, basketball, or simply walking around outside, it's crucial to have an accurate WBGT reading. If the temperature is too high based on this reading, you're at risk of suffering from heatstroke and other heat related illnesses that put your life at risk.

Use Zelus to take daily measurements, keep track of data, and skip outdoor practice when it's simply too hot for training and other outdoor activities.

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. I checked the readings against a handheld and they are either identical or very close. So far, so good.
