### 1/5 — Additional Equipment Necessary

*2026-05-27*

I so wish I could give 1/2 to 0  stars, for the rating. 
It would be nice if they’d tell you about this additional equipment, this prior to downloading, and  try to set it up. 
Theres no indication even as to what is needed, where to purchase it, and it doesn’t work with iPhone. 
Useless, and I agree with other users as to why Apple would even recommend this app!
Deleting as soon as I post this review!

### 1/5 — One of the worst User interface and unreliable reading

*2026-05-10*

Worst app ever made

### 1/5 — Não funciona

*2026-05-02*

Não conecta com o relogio

### 1/5 — Nao fuciona

*2026-03-30*

Todos os dados vc tem que inserir, nao justifica o APP sem utilização pratica

### 1/5 — Бессмысленно

*2026-01-16*

Не работает с часами от Apple

### 1/5 — Don’t buy

*2026-01-12, version 4.0.0*

The links to buy the device don’t work and they don’t exist. I looked it up and I get nothing

### 1/5 — Does not pair

*2026-01-04*

Does nothing and you cant change language. Very bad app. Too simple.

### 1/5 — Delete

*2025-09-05, version 4.0.0*

Remove this app from the App Store as you need another device to monitor your temperature but that device is no longer being sold. The app is useless.

### 1/5 — What

*2025-07-11, version 4.0.0*

This app is recommended under the Health / watch app and yet, it seems to pair with its own device and not with the Apple Watch. Misleading and useless.

### 5/5 — 5 year review

*2025-04-25*

Had this thermometer since 2020 and have used it on both of my children. The reading is always similar to our handheld thermometer. My sense-u thermometer stopped working after a year despite being so darn expensive. But our ithermonitor keeps on working. I love this thermometer, I wish it wasn’t discontinued.
