### 5/5 — Best device for SpO2

*2026-01-10*

I’ve looked extensively and I think this is the best device for continuously measuring SpO2 - it provides more granular data than Oura

### 2/5 — Syncing with Health

*2025-01-12*

The app is nice; however, it would be better if I could explore the data either via a data export or a cursor, like the o2vibe app had, and if it would send all data to Apple’s Health App. Some of the data are there, but most are not. Of course, the issue could be on Apple’s end, but this shortcoming is disappointing, as the app’s ability to sync with Apple’s Health suite was a critical part of my decision to purchase the Circul+ ring.

Edit: I decided to lower my rating, because the Sleep Report will give a lowest SpO2 value, but this value does not appear on the chart/graph, meaning I cannot tell *when* this dip occurred, which is critically important information (i.e., I need to be able to ascertain if the dip occurred when I got out of bed and walked around or while I was asleep).

### 3/5 — Syncing with Health

*2025-01-01*

The app is nice; however, it would be better if I could explore the data either via a data export or a cursor, like the o2vibe app had, and if it would send all data to Apple’s Health App. Some of the data are there, but most are not. Of course, the issue could be on Apple’s end, but this shortcoming is disappointing, as the app’s ability to sync with Apple’s Health suite was a critical part of my decision to purchase the Circul+ ring.

### 4/5 — So far so good

*2024-11-08*

I have chronic apoxemia due to other factors but I needed something to accurately measure my o2 stats continuously and alarm me when they fall. It’s doing that but I don’t always get the alarm and not sure why. It seems to be reasonably accurate. Charging is clumsy and hope that is improved.

### 1/5 — Not worth the price

*2024-04-05*

4 out of 5 readings come back as failures

### 1/5 — Errors in least update

*2023-11-02*

The calculation for ODI has changed dramatically in the last update. Please verify if it is an error. My ODI went from 5 to over 30 since update on Oct 28, 2023

### 1/5 — Shows some promise but no customer support

*2023-08-12*

The prevention ring shows some promise but no customer support when issues arise.
I’ve tried to contact several times; I’ve registered both rings I purchased but still no assistance when I found issues in the data and behavior of each ring.
Expensive “toy” and too bad - I was hoping to get some useful data. For myself & my spouse.
 How can I trust Circul data over bp cuff or oximeter or Oura ring?

### 1/5 — Save your money

*2023-04-23*

All zi Can say is it didn’t take long to return it. I don’t believe the readings are neat accurate. The app is crap

### 5/5 — My Health

*2022-05-06*

The circul ring has provided me with the information about my health that I have always wanted 
It really has been a great device in controlling my anxieties

### 3/5 — Wish it was Apple Watch compatible

*2022-02-11*

I really wish this app would work with Apple Watch. I have to get into the app from my phone and it can be inconvenient a lot of times with my work.. :(
