### 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.

### 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….

### 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.

### 5/5 — Great app

*2026-05-20, version 3.3.0*

Great app

### 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.
