HeatSafe WBGT
Live heat-risk & WBGT safety
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Know when heat becomes dangerous. HeatSafe shows live Wet Bulb Globe Temperature and clear, color-coded safety guidance for your exact location.
HeatSafe turns complex heat science into a simple answer: how dangerous is the heat right now, and what should you do about it?
Most weather apps only show temperature. But how hot it *feels* — and how risky it is for your body — depends on humidity, sun, and wind too. HeatSafe uses Wet Bulb Globe Temperature (WBGT), the same heat-stress measure trusted by athletic trainers, the military, and outdoor workers, to give you a clear read on real heat risk.
FEATURES
• Live WBGT estimate for your current GPS location
• Clear, color-coded risk levels with plain-language safety guidance
• Hourly outlook so you can plan workouts, games, and outdoor work
• Save your favorite locations and check conditions anywhere
• Works worldwide using Open-Meteo forecast data, with extra detail from the National Weather Service in the United States
• Fast, lightweight, and privacy-friendly — no account required
WHO IT'S FOR
• Athletes, coaches, and parents at youth sports
• Runners, hikers, cyclists, and golfers
• Outdoor and construction workers
• Anyone who wants to stay safe when it's hot and humid
