### 3/5 — Same levels every day.

*2025-09-14*

Exactly the same pulse and oxygen level for every day for over a month. How is that possible?

### 3/5 — For Five Stars.

*2025-08-15*

I have several ways to keep track of my daytime Spo2. What this one could use is a place for a note with each entry. It's important that I keep track of conditions related to each reading.

### 5/5 — Excellent

*2025-06-16*

Impressive work!!

### 2/5 — Useless

*2025-04-12*

No purpose

### 1/5 — It doesn’t work

*2025-04-02*

It doesn’t record anything.

### 1/5 — Deceiving

*2025-02-27, version 1.21*

Nowhere on the App Store or in the details does it say you need to pay £30 a month. Definitely a scam

### 1/5 — Doesn’t work…..

*2024-12-28, version 1.20*

I have been using this for some time without any problems until recently. It’s just stopped working. It flickers and freezes, obviously needs an update.
Just unusable currently. It’s been 2-3 months I thought give it time and the developer would fix it, they haven’t.

### 5/5 — Rty

*2024-06-17, version 1.17*

Uvhh

### 1/5 — Richard

*2024-01-15*

Can’t figure out how to make it work

### 1/5 — App

*2024-01-05*

Does not work. Do not charge me
