Review summary

User reviews converge on reliability and usability issues: spots of strong comfort and ongoing development contrast with frequent connectivity failures, data inaccuracies, app crashes, and rapid battery drain. Several users lament the removal of real-time SpO2 data and other health metrics, while others note the UI is overly complex and data-dense. Overall sentiment is negative due to consistency and data issues, with limited positives about fit and ongoing updates.

Pros

Comfortable design with adaptive fit
Ongoing app/firmware updates and positive signs from the developer (per user), indicating active development

Cons

Frequent connectivity/sync issues between the ring and the app
Inaccurate or unreliable readings and data quality problems
App instability including crashes, resets, and loss of data
Short battery life and charging problems
Removal of real-time SpO2 and other health data/features

2026-07-18	Sh*****	Since the last update the app crashes and says the ring is disconnected also noticing the battery life is shorter.

2026-06-24	Oc*****	There is nothing more frustrating than getting a brand new product. Downloading the app, trying to set up an account, and then getting a service exception that won't let me proceed. So, this brand new ring I was eager to try is essentially useless — I can’t use it or get data from it. I have no idea what data it even collects. Very disappointing.

2026-06-06	hg*****	You guys need to do an update I’ve had my ring for eight months with no problems and you keep doing updates and it gets worse every time the red light on my ring doesn’t even light up anymore so it doesn’t give me my heart rate or SPO2 it’s still tracking data, but the app keeps crashing so you might want to do an update. I don’t know if my ring is broken, but how am I supposed to get in touch to troubleshoot?

2026-05-18	Pe*****	The ring advertising “record every beat” but there is no way to view that data within the app or anywhere else. The app only lets you see 10 minute averages and gives no access to the raw data. It doesn’t write to Apple health every 1 minute which is more often than Apple Watch. However, If you are in a workout it silos all health data and does not write it to Apple Watch. This completely defeats the purpose of using the ring during a workout because you need it to write to Apple health so you can read the data. Further, it auto detects workouts and doesn’t allow you to turn that feature off. Currently, there does not appear to be any way to get heart rate data during a workout from the ring to Apple health. I would change my review under 2 circumstances. 1. All the data to push to Apple health during a workout in the same way it does during sleep and outside activities. 2. Give access to the raw data. If it records every best, show it! Otherwise how are we supposed to take it seriously. Both of these would make the ring much more usable.

2026-02-28	De*****	Not sure the bad reviews. This app only works with their smart ring. So far really like what I am seeing. Biggest complaint is that there is too much data. Hard to digest. I want them to keep the data as some of us like it but should have a more easy to read up from ui that calls out trends, positive and quick access to key data. Also having the ability to edit the front screen. The circul sense team is quick on replying to my support questions. Work is actively being done on the app and firmware of the device. Can't wait to see what is coming next.

2026-02-02	Ho*****	The CIRCUL Ring worked for the past 4 weeks but, as of two days ago, I am Not getting any Readings from the CIRCUL App. Please do an Update for this. Now my CIRCUL Ring is Not lighting up Green. And I charged it all night. Who do I call to rectify this situation?

2026-01-11	BI*****	The ring and app are just a ploy so you buy a ring. When the ring was new it and the app seemed pretty all right. Now the ring battery dies after 6 hours. It is always trying to connect. That being said, for the month it appeared to work correctly the information was beyond innacurrate. I put it up against some calibrated medical equipment and all readings were way off (90%). Don't buy the ring or use the app. I really wanted to like this. Especially the SPo2 and BP functions. It does not even have the SPo2 function anymore and you have to calibrate the BP function so often, you might as well use a cuff.

2026-01-09	Mh*****	Ring seems to collect good data but the app is horrible. So overly complicated. Only “uploads reports” periodically so you have to wait each time you check app. Keeps asking to validate the blood pressure so i have no idea if the reading is accurate or not. It’s a shame because the ring is comfy and nice looking.
