## OSHA Reviews in United States

### ***** "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!
-- blessed, forgiven, saved!, 2024-08-02

### ***** "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.
-- turtle brooks, 2024-08-01

### **--- "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.
-- 1wildchild8, 2024-07-31

### ***** "It’s been updated"
Had an issue that wouldn’t allow me to open it. It’s fixed now so everything’s kosher on my end
-- GrannysMoistToe, 2024-07-19

### *---- "Needs a lot of work"
Concept is great, but only having hourly forecast and not realtime does not help.
-- mbarker, 2024-07-07

### *---- "App not working properly"
Haven’t been able to retrieve weather data in days. What’s up?
-- Jolyfena, 2024-06-28

### *---- "“Conditions are potentially dangerous”"
When is this EVER not the case?
-- wittol2b, 2024-06-25

### *---- "Seems to be, not reliable"
This is always off and showing less heat, other apps more accurate in my opinion. Sometimes it just doesn’t work
-- Soto J., 2024-06-18

### ****- "Watch app"
Need a watch app with notifications
-- wasted time..., 2024-06-18

### *---- "Not accurate"
Doesn’t work. Extreme risk but actual conditions are cold and rainy.
-- bill d'cat, 2024-06-17

### ****- "UV"
Will you be adding the UV index to the app?
-- Mike outdoor, 2024-06-17

### *---- "Unusable"
I have been using this app for years, now it won’t connect to get weather data. Just keeps trying to connect.
-- TacMedic708, 2024-06-04

### *---- "Connection Error"
We’re told to use this app at work and  it never works right. First it wouldn’t open for weeks. It worked for a week after being updated and now it just won’t show any data. This is on both phones and the 15 other guys in my group.
-- oaklandr, 2024-06-04

### ***** "Auto closes."
*Update* The heat index app is now working as it should. Thank you for fixing it! 
App isn’t working, it auto closes, please fix so I can check the heat index again
-- Mom in SWFL, 2024-05-25

### ***** "App back to its trusted condition"
I am a safety manager and have used this for years.
-- treetopper75, 2024-05-25

### ***** "Back up and running - Thank you"
Thank you for the great Tool
-- AkaClyde2, 2024-05-21

### *---- "Immediately crashes. PLEASE FIX"
I used to recommend this all the time during trainings. Now it just immediately crashes. Please fix it
-- Stressed Overworked RN, 2024-05-14

### *---- "Crashing"
The index tab crashes every time. This is just in the last month. Useless without that tab working.
-- Mjdl aedfhg, 2024-05-14

### *---- "Doesn’t Work"
This app hasn’t worked for the past three weeks. Crashes as soon as it opens.
-- Office Drone 867, 2024-05-14

### *---- "Crashes"
App crashes when trying to load.
