The app seems to be very accurate compared to how I normally calculate Heat Index by hand. I guess if you didn't want to use this app, which targets your individual location. you could use one of the generic calculators and enter in your own data. I'll keep checking this from time to time, but the only thing that seems to be missing is the taking into account the effect of the sunlight, unless perhaps, I have missed that.

Temperature readings are not always up to date, so I might underestimate the risk. The calculator option can make up for this, but only if the temperature and humidity ratings are known values. Otherwise, information is clear and easy to use. If the weather readings would update to current conditions, I'd give 5 stars.

This app is never correct in temperature, heat index or location. You can stand next to 3 other people with the app open and all 4 will show something different. When local weather says its 115°f and this app says it's only 101°f obviously there is something wrong. The information given to help treat symptoms is spot on but everything else is terrible.
