Heat stress and wet bulb temperature at a glance
Wet Bulb Widget shows you the current wet bulb temperature — the single number that tells you how dangerous the heat actually is, combining temperature and humidity the way your body experiences them.
Add it to your Home Screen or Lock Screen and see it at a glance. Danger bands are grounded in real physiological research (Vecellio et al., Penn State HEAT Project, 2022) rather than the outdated theoretical limits most heat-safety tools still use.
• Home Screen and Lock Screen widgets
• Trend history and forecast
• Air temperature, humidity, and heat index alongside wet bulb
• Search any location, or use your current one
A 30-day free trial, then a one-time $1.99 unlock — no subscription, ever.
