  • Awesome but could be better May 29, 2018

    By Huntress101
    This app it awesome but I won’t give 5 stars. Because it should give you notifications of warnings or have a alarm of high heat index to tell you you need to get inside.

    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.

  • Good overall but needs a few tweaks Jun 28, 2017

    By Jigs-n-fixtures
    It works well. A previous review had an issue with the weather data not matching weather apps, but that is easily edited onscreen so it isn't an issue to me. I do wish you could input geocoordinates, for the location. This is an issue for me and my workers because we work in somewhat remote locations. Maybe in the next release

    This app was working great until this last week. Then it couldn't find location no matter what I did. I tried uninstalling then re-installing several times with no luck. It finally began working again today. It is a great tool when it works.

  • Numbers are off Jun 4, 2020

    By TexHeat2020
    Used this app successfully last two years. It always matched the temperature and humidity for an accurate calculation. This year it’s off by several degrees. This is dangerous for me because I have a medical condition and must be inside when heat index reaches 104. Will have to look for another app that is more accurate. Very disappointed.

    I used this app a couple years ago and was great. I tried downloading to use, it downloads, installs and asks to use location, yes. All I get is a black screen. Not satisfied!

    Basic heat index if you wear gear the limits are lower you can't add any risk factors. Like coveralls FR, green gear, yellow gear, tyvek, Hazmat suit, fresh air, fully encapsulated suit ect. In full sun,in shade, next to hot Equipment.

    I need this for my job to justify any variations from time used for completing duties — however the heat indexes on this ap are lower than both Weather Underground and The Weather Channel — how are they all not the same? Is this giving inaccurate data?

    Worked great until today, July 8th, 2020. No longer automatically finds location or accept keypad inputs. No luck deleting and reinstalling. I hope this issue is resolved soon.

  • Great App BUT Needs Spanish Mar 26, 2018

    By MarroKing
    Great app overall. It just needs to have the option of switching it to Spanish mode. Or better yet make a separate Spanish one for FLC contractors and supervisors. That would be deeply appreciated. Thanks

    Automatic calculate HI using area temp/Rh. Great app. Also, good references for heat related injuries, prevention, & treatment.

  • App is worth downloading Jul 3, 2019

    By banthonyc
    The app is great. Need to understand that the heat index is measured in shade with a light wind and may not be exact according to where someone is working. If in direct sunlight it will be 10-15 degrees hotter potentially. A good tool to generally understand the heat index and begin safety precautions. Wish it forecasted out a week.

    Updated my previous review. App now functions properly after they released updates. I will be sending app info to my regional maintenance supervisor to send out to all properties.

    By Juan Hungman
    How can it be 77 but feel like 78 with 86% humidity??? Weather app says it feels like 87 which is a lot closer to accurate. I’d expect a lot better from something claiming to be OSHA. For the time being, use a weather app to get your temps for safe working

    Used to work great. Now it attempts to load data and crashes. This is happening ion 2 separate iPhone 7 (iOS 12.4). Does not even fully open before it crashes. Removed and reinstalled with same results.

    Not very accurate... first day installing, the actual temp out side was 107° and I download this app to check the index . it said current temperatures were 100, low risk... the actual heat index was 110. im dealing with small children outside, this needs to be accurate!

  • Embarrassing Jul 10, 2018

    By 3rdRail
    This app is constantly 7-10 degrees cooler than the actual temperature. I don’t know how it’s possible to be that far off or where this app gets it’s info, but it’s embarrassing for OSHA. Especially considering that the app is designed to help people work safely in hot temperatures.
