Valuable !!

It’s a the right Tool!
It’s useful and I’m smarter dealing with the heat.
( I’m proactively plan for this summer heat wave)

Not updating/Loading

App was perfect with location and temperatures. I loved the gauge to tell you if you were in danger or needed to take precaution. The past week it has not loaded or updated. Please fix.

Great tool for everyone

I travel the country and have referred to this app in many places.
It is always precise, accurate and very helpful.
I love the precautionary, symptom and fist aide tabs…..
Also available in Spanish so communication is not an issue.
Love it and share it with everyone!

Works for me

I work outside , middle of day, middle of summer every year all year. Have had this app for about 5 months now and it is my go to. Allows me to avoid days that are in extreme, shows what symptoms to look out for in heat related health issues and what to do when they happen. Breaks it down hourly, the temp and “feels like” categories. It overall I like this app.

Constant Errors

Ironically this app only seems to work when you aren’t in a danger zone for heat index. I use this app for work and every time time we check around noon or when we know the heat index should be high the app has an error. I have it two stars because when the app works it’s very good, but in an error state you can’t even look at the other tabs like symptoms.
