HeatShield Worker App

HeatShield pairs a worker's smartwatch with a supervisor dashboard so heat-stress warnings reach the right person quickly. The app shows your vitals, pairs your watch and tells you what to do: seek shade, drink water, rest or stop work.

Install in 4 steps

Tap the download button. If Chrome says “This type of file can harm your device”, choose Download anyway (it warns about every APK that is not from the Play Store).
Open the downloaded file. If Android asks, allow Install unknown apps for Chrome (Settings → Apps → Chrome → Install unknown apps).
Uninstall any older HeatShield version first if the install is refused (updates from a different signing key cannot install over it).
Open the app, sign in, allow Notifications and Display over other apps (needed for the stop-work alert), then pair your watch.

Your data, in short

The app and watch send your heart rate, skin temperature and the surrounding heat and humidity to your supervisor's dashboard so they can act on a heat warning. The app asks for your agreement before anything is uploaded. Read the full Privacy Policy.
