## What is Heat Index & Wet Bulb Monitor?

Know the heat risk where you are—at a glance.

Heat Index & Wet Bulb Monitor calculates the National Weather Service heat index and brings the numbers that matter together in one clear view.

KEY METRICS
• Heat index with published risk levels
• Wet-bulb temperature
• Estimated WBGT
• Air temperature and humidity
• Dew point and UV index

HEAT-SAFETY GUIDANCE
See the current risk band, understand what it means, and view practical work/rest guidance based on your selected workload.

HOME SCREEN WIDGETS
Check the current heat index and related metrics without opening the app. Small, medium, and Lock Screen widgets keep heat risk visible throughout the day.

LIGHT AND DARK APPEARANCE
Use the appearance that works best for you, with clear gauges and readable risk levels in either mode.

PUBLISHED METHODS
The app explains how heat index, wet-bulb temperature, and estimated WBGT are calculated. Estimated WBGT uses weather data and a documented solar estimate; it is not a substitute for an on-site WBGT instrument.

PRIVACY FIRST
No account, no ads, and no tracking.

Heat conditions can change quickly. Follow official local warnings and workplace safety requirements when planning outdoor activity.


## Version history (last 2 releases)

### 1.0.1 — 2026-08-24

Fixed: the widget could show an old reading.

It only ever updated while you had the app open, so if you hadn't opened Heat Index in a while the widget kept showing whatever it last saw — sometimes days old, with nothing to tell you it was stale. It now refreshes on its own in the background.

### 1.0 — 2026-08-15

No release notes.
