User Reviews

Users praise Circul+ for its core capability: continuous SpO2 measurement and broad health metrics (sleep, HR, steps, temperature). The ring is described as providing granular SpO2 data and easy setup of the app. However, frequent issues across reviews include limited Apple Health integration (most data does not sync or export), reliability problems (frequent reading failures and unreliable alarms/auto-start-stop), poor customer support, and a clunky UI with occasional data discrepancies after updates.

Pros

Continuous SpO2 measurement with granular data.
Broad health metric tracking (sleep, heart rate, steps, temperature) alongside SpO2.
App is easy to set up and use.

Cons

Limited/incorrect Apple Health integration: most data does not sync or export.
Reliability problems: frequent reading failures and inconsistent data.
Alarm not reliably triggering and auto-start/stop feature failing.
Poor customer support.
Clunky UI/navigation with occasional data discrepancies after updates.

Recent reviews

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

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.
