1. 3/5Helps has Alarm which is great

   Need to be updated, when in danger it should read on same page when working outside in direct sunlight breaks should be rotated ever XYZ minutes, drink xyz liquid and shade. Also there should be the OSHA rule on the app. Reminders to everyone what happens if you have heat stroke or exhaustion. The part not talked about is after recovery, how you can no longer take the heat as you did. How this illness does XYZ to the body . Many do not know, and until educated wont. Unfortunately we can’t rely on all companies having the training resources. So at a minimum OSHA should add training to app., this I can promise will save a life and a few from getting the illness. That’s all you need is one to make this app pay itself off and 5 star rating. Chris South Carolina

2. 5/5Works 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.

3. 5/5Perfect quick reference

   With work not having a heat break schedule in place, I would like to start using this simple tool as a reference to when it gets too hot. I’d like to request a push notification feature for when hazards reach the warning and danger zones. Or a heat index we can set based on our company heat break policy, if it gets established.

4. 2/5Constant 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.

5. 1/5Don’t use

   The app doesn’t actually adjust throughout the day to what the actual temperature and humidity is, just what the forecast was. Right now, it says it’s 86 with a heat index of 92. But some showers that weren’t forecasted came through this morning and the temperature at the moment is actually only 80. So while it was forecasted to be 86 right now, it’s only 80 and the app says it’s currently 86 out. This can be incredibly dangerous if people are relying on this app and the temperature or humidity ends up being higher than originally forecasted. Do not rely on this app at all, basically just use it as a heat index calculator
