I just wish there were less paywalled features. ### 2/5 — Buggy *2025-07-17* Wanted to like this app but it has issues. Entering cities in Alaska causes the app to crash. No matter what your city’s temperature is, even in the 60s, the heat zone shows in the “potentially dangerous” yellow range. **Developer response:** For some cold locations in Alaska, the National Weather Service doesn't regularly publish wet bulb temperatures, and we've updated the app to properly handle those locations. Thank you for your feedback. ### 4/5 — Worked GREAT until a couple days ago? *2024-08-29, version 2.0.2* This has been my go-to app for heat index/wet bulb temps — straight-forward, simple graphics, etc. But all of a sudden it “attempts” to retrieve the info but fails to provide it. I’ve done nothing different, it — just — stopped — working. Major bummer. ### 3/5 — Not working *2024-08-21, version 2.0.2* Only worked and showed values 1 of 8 times I tried to use it. In a place with a strong signal but I just got the wheel of death 7/8 times. ### 1/5 — Does Not Work *2024-08-19, version 2.0.1* App was fine when I first got it. Now it never updates when asked to get latest readings. Just get the Pinwheel of Death. The app doesn’t help anyone if it doesn’t work. ### 1/5 — Not Working *2024-08-19, version 2.0.1* It worked one time, and hasn’t refreshed or updated again. ### 1/5 — App keeps crashing *2024-08-05, version 2.0.0* I keep having the same problem. When I press “Get Heat Safety Assessment,” the app just crashes. I’ve deleted and redownloaded the app, and it does the same thing. Cant even get the WBGT anymore. ### 1/5 — Doesn’t work! *2024-07-31, version 2.0.0* I put in address for my current location and hit the button to show the heat, and it will kick me off the app, worked a couple times now doesn’t! ### 1/5 — App Keeps Crashing *2024-07-31, version 2.0.0* App worked good when I first downloaded it. Today the app crashes every time I hit “get heat safety assessment” and no update is needed. Please advise. ### 1/5 — Location stinks *2024-07-16, version 1.2.2* Tells me the same forecast regardless of the city I put in. ### 1/5 — Doesn’t work *2024-06-21, version 1.2.0* I put in my zip code. They then changed it to coordinates and nothing other than that happened. I’ve tried multiple times and the app is completely blank other than showing my coordinates. Glad I didn’t pay anything. ### 1/5 — Not Working *2024-06-21* This app was great for two days until it suddenly stopped working, so I purchased it thinking it might have been a trial version, but it still doesn’t work. Blank page reads “ last attempt on whatever date” please fix or refund. **Developer response:** The temporary outage was due to a service interruption at NOAA and it has since been resolved. Thank you for the feedback. ### 1/5 — App issues *2024-06-09* Cannot see location or any setting information. Will still populate information on index temps but who knows where it is populating them from. Fix so we can see what’s wrote in the app and I’ll change rating. Response to developer response: I can click the pin location and stuff like that however no text will populate in the app for location or anything like that so I don’t know where exactly my info is being pulled from. Also when I go into settings there is no text visible. Only the toggles are visible. **Developer response:** We've updated the app to fix this problem, which occurs when using a dark theme. Thank you for pointing this out. ## Most critical reviews (10 lowest-rated) ### 1/5 — EXTREMELY inaccurate *2026-07-01, version 3.4.2* The app shows current temp 91f, RH 54%. Wet bulb SHOULD be 78f, but the app shows 87f. That’s just WRONG. ### 1/5 — Extreme long loading times *2026-07-01, version 3.4.2* Extreme long loading times ### 1/5 — App sucks on iphone *2026-06-29, version 3.4.2* This app would be good if it works on the iPhone, but it sucks the big D on the iPhone, the wet bulb pops up for a second and then it disappear ### 1/5 — Used to work *2026-06-27, version 3.4.2* I used to love this app. But now it won’t stay on to even see it. It blinks info and then goes blank. Thought of paying for it but others who have paid have same problem ### 1/5 — app not working (paid) *2026-06-14, version 3.4.2* app shows data for a second, then screen goes white. ### 1/5 — Location is jumpy *2026-06-12, version 3.4.2* The location keeps changing and I cannot manuallyy enter my zip ### 1/5 — No longer usable *2026-06-10, version 3.4.0* Ads made this app difficult to use, so I paid $6.99 and the app fails to load data. I’ve tried restating the app, uninstalling and reinstalling, waiting a few minutes, and it continues to preform unsatisfactory. The data will appear for a split second and then black out. ### 1/5 — Doesn’t always work *2025-08-15, version 2.0.4* Won’t pull up report every time ### 1/5 — Doesn’t work all the time *2024-08-28, version 2.0.2* Will not give readings all the time. ### 1/5 — No Reading *2024-08-20, version 2.0.2* I can’t get the app to work. ## Most praised reviews (10 highest-rated) ### 5/5 — Finally- wet bulb temp forecast *2026-06-13, version 3.4.2* No nonsense…. Delivers wet bulb globe temp now and 4 day projections to plan outdoor activities…. ### 5/5 — Great app *2026-05-20, version 3.3.0* Great app ### 5/5 — Easy to use. Good info for a runner…and a chemical engineer *2025-08-18, version 2.0.4* I use this app to get the WBGT before I exercise outside, or when I’m spot checking the cooling capacity of a cooling tower ### 5/5 — Easy to use. Good info for a runner *2025-07-19* I use this app to get the WBGT before I run/excercise outdoors on a hot day! The app is reliable and easy to use ### 5/5 — Very useful for summer *2024-06-24, version 1.2.1* Revised review: the app is really useful and easy. There was an outage for a day or two with the weather service but that has been remedied and is working now. Developer was very responsive. ### 5/5 — Great app! *2024-06-12, version 1.2.0* App works perfect after latest update! Does exactly what I need it to! Goes off of long/lat. excellent app! ### 5/5 — Good app! *2024-05-28, version 1.1.2* I’ve been using this app now for a couple of months. So far the app hasn’t crashed on me and it has worked well. This app helps me understand what the heat index is going to be. I need that information to help employees stay safe. ### 5/5 — Not working *2024-05-09, version 1.1.1* Cant go in No access ### 5/5 — Fabulous App *2024-04-21, version 1.1.0* Last summer I went to hospital emergency for two days after suffering Heat Stroke. The Heat Safety app gives me current weather conditions to help me to avoid another Heat Stroke. ### 4/5 — Bugs fixed, thanks! *2025-08-20, version 2.0.5* Upgrading my 2-star review to 4 stars because the latest version fixed a crash problem and also the place search. It now works well to indicate heat risk where you are or elsewhere in the US (only). Upgrade to ad-free was worth it for me. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
