CIRCUL+

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).

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.

4 out of 5 readings come back as failures

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

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?

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

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

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.. :(

And poor user interface on app. I have reached out to the company twice for help to keep the device connected to anything! So far crickets. Seems the support team is as useless as the device itself. I will ask for a refund. Buyer beware this is not what you think it is. The user interface on the app is not intuitive. It clunky and difficult to navigate. I am unable to find information and instructions about how to best navigate or set up the device and what the readings actually mean. Zero customer service or response. Useless

Not connecting or constantly syncing data. Willing to change my review if I get some support but thus far I’m not impressed. Could be a awesome device once the bugs work out
