### 3/5 — Great

*2026-05-19, version 1.4.2*

Very helpful

### 3/5 — Good

*2026-05-15*

I like the app. It’s very comprehensive.  But there’s no consistency to when it tracks the oxygen.  Does it only work at night??  Why aren’t there regular readings during the day.   I breathe all day long!  I need to know why it’s not a consistent reading of oxygen all day long.

### 5/5 — Excellent App!

*2026-04-18*

I’m so pleased with this app - it’s really good for monitoring vitals such as resting heart rate, HRV etc and giving an overview of health as well as allowing me to dive into those metrics in more detail. What’s more and what sets this app apart in my opinion is the fact it has a useful selection of breathwork exercises to help improve the stats. Really now one of my favourite health apps because it has data + tools!

### 2/5 — Not measuring up

*2026-04-17, version 1.4.1*

Several times my oxygen dropped to the 70’s but it never alerted me. I’m supposed to be alerted if it drops below 93 and rarely does it alert me

### 4/5 — Very helpful, but please save graphs

*2026-04-12*

Love this app for tracking my SpO2 while sleeping. I get a clear picture of the difference between wearing my CPAP and not. However, I wish it would save the information in the graphical form it displays for each 24-hour period. This would allow me to access graphs from previous nights to show my sleep doctor.

### 5/5 — 真心不错

*2026-04-09*

实时监测功能不错，哪怕是免费版也把功能做的较为齐全。

### 5/5 — Useless app!

*2026-04-06*

If I have to read my own spo2 and write it in the journal, this app isn’t worth a penny!

### 5/5 — Nice interface

*2026-04-06*

Still trying to get all of my devices synced; don’t want to add anything manually if possible

### 3/5 — Oxygen

*2026-04-01, version 1.4.1*

Doesn't work consistently

### 5/5 — Life saver for hypoxemia

*2026-03-23*

I had bought Apple Watch to use the oxygen level measurement as I suffer from hypoxemia, I was diagnosed some weeks back. 

The app sends push notifications on my iPhone of my oxygen levels and can be configured to send low below 95% notifications which are handy at night as if I wake up in the night I can instantly see the notifications from outside which alleviate a lot of anxiety. 

Excellent service from the developer too, responded quickly to my question on hrv.

### 5/5 — Évaluation du logiciel.

*2026-03-20*

Très satisfait.

### 5/5 — 好用、专业的健康监测软件

*2026-03-14*

好用、专业的健康监测软件，就是价格有点高

### 5/5 — easy setup for watch and spo2 reminders work well

*2026-03-02*

I have been suffering from hypoxemia and that oxygen tracker along with Ecg was the reason to get the watch. 

The app syncs easily with watch spo2 readings and best part is it sends notifications on oxygen levels even at midnight. 

All the oxygen readings of watch are saved and displayed chronologically and in graph display which is properly done, nothing out of ordinary but well executed. 

I hope a feature to trigger oxygen readings at regular intervals is also made.

### 5/5 — 设计有点复杂

总体还好

### 4/5 — 差个脉搏

### 1/5 — Update 04.09

*2026-09-04*

Nachdem Update ist die App nicht nutzbar bzw. werden keine Daten mehr angezeigt. Auch eine Neuinstallation brachte keinen Erfolg.

### 1/5 — Can not tell what the current levels are , why does it ask to record the level, when you are unsure

*2026-06-27*

Just record the level, do not have the consumer do it. They do not know where you are pulling the data from. What is current and what is past.

### 1/5 — Viel zu teuer

*2026-06-16*

Die Werte sind sehr fragwürdig (z.B. sehr hoher Stresslevel beim chillen auf dem Sofa) zudem die Premium-Funktion viel zu teuer

### 1/5 — Disappointed

*2025-11-15, version 1.3.1*

I bought app because it’s supposed to give notifications when blood oxygen drops below a set amount. This never worked.
