## Most critical reviews (6 lowest-rated)

### 1/5 — bad timezone?

*2025-07-23*

the date is wrong. even though the device’s time do get synced when my phone connects to it. the app seems to be plotting the data in a default timezone.

### 1/5 — For real?

*2024-12-25*

This app is a joke

### 1/5 — Terrible product and app

*2024-03-05*

Terrible product and app, with a fake review on Amazon and a bunch of non-English reviews for completely different products.  Steer clear, if you already bought it, send it back.

### 3/5 — Does the basic ob...a couple suggestions

*2022-01-05*

The app sets up, connects easily and works fine on Day 1, so I have yet to test the data recordng features.  

Also, when I select a measurement in the app and select today's date, a dialog box opens that is in Chineses Characters with OK button. I have no clue as what this says while the app is displayed in English.  I select OK, and nothing is graphed, so I assume it is a No Data Collected notification. 

Your instructions nor the App speak to what the sampling rate is, however, I will assume it is an hourly setting based on leaflet images. 

Needed addition:  Must add the ability to change C to F in the app.  Changing on the device does not change this in the app, nor does there seem the ability to change C to F in this app

Suggestion:  Add data export function, like Send to email, save file etc. 

Suggestion: The ability to change and set Sample rate frequency

### 5/5 — Easiest app set up ever.

*2023-07-21*

Turn on monitor , download app, , it starts displaying the results, Humidity always reads 99% but what can you say
