Heat is the silent emergency.
Meet it ready.
HeatGuard tells you how dangerous the heat is right now, points you to the nearest place to cool down, reminds you to check the back seat, and puts help one press away — built in Tempe, Arizona for the people heat hits hardest.

Rare, long-lasting heat. Everyone at risk.

Hold-to-activate SOS
The center of the app, always one press away. Hold to send your emergency contacts a text with your location — designed to work even when your signal is weak and you’re offline.
Cool Spots
Live cooling centers and hydration stations from the Maricopa County Heat Relief Network — with hours, so you don’t drive to a closed door.
Vehicle Heat Alert
On hot days, a reminder to look in the back seat — for kids, pets and anyone who can’t get out on their own.
Daily check-in & heat buddy
Choose one to three check-ins a day. Share “I’m OK” with the person who looks out for you — and a quick safety check for water, medicine, a cool home and a charged phone.
Plan before you go
Activity prep for hiking, fishing, sports and walks, plus a trip check-in so someone knows when you should be back.
Works offline
Power outage or dead zone, your emergency card, saved cool spots and last forecast stay on your phone.
Made around the people you protect
Add kids, older parents and pets to your profile, tell HeatGuard about your home’s cooling, and your alerts stay relevant to your household — not generic.
Built for the people heat hits first.
Heat doesn’t affect everyone the same way. HeatGuard asks a few quick questions and shapes Home around your life.

Official guidance. Not our guess.
HeatGuard doesn’t invent its own danger score. The risk level on your Home screen is the National Weather Service HeatRisk category for where you are, right now — the same for everyone. Your profile only adds what to watch for.
With a heads-up when it’s going to climb later today.
A color-coded card you can read in a glance.
Forecasts and cooling locations come from public agencies.
