## CIRCUL RING Reviews in United States

### *---- "NOT WORKING"
My ring is not working after less than 3 months usage. I have tried repairing with Bluetooth, deleting app and reinstalling, turning off phone, unbinding and repairing with app, everything that has been suggested online. I liked things until 2 days ago when sleep and temperature stopped recording and now the ring won’t work at all. Very frustrating to pay for something that only works for a short time. Please help.
-- KT Lang, 2026-09-18

### ***-- "Nice Sleep Tracker"
I’ve used a Circul Ring 2 for 11 months and found the following:

The adaptive fit is great and the ring stays put on my finger. I have to wear it halfway between my knuckles for it to get reliable blood oxygen data, however.

Daytime metrics are unreliable and the app is buggy for workouts. I ended up using the ring only for sleep tracking and use an Apple Watch during the day.

Sleep metrics are excellent, including heart rate HRV, blood oxygen and skin temperature.

The analysis is pretty good, and they provide some nice statistics and graphs of my sleep performance. There is also limited Apple Health data transfer. 

I would prefer, however if the Circul app sent all metrics to Apple Health so they can combine that with my Apple Watch data and provide a more comprehensive health overview.
-- KurtinBoston, 2026-07-23

### ****- "Ring Is Great App needs work"
Since the last update the app crashes and says the ring is disconnected also noticing the battery life is shorter.
-- Shadow77ny, 2026-07-18

### *---- "Service exception"
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.
-- Ocboater, 2026-06-24

### ***-- "Crashing"
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?
-- hgg101, 2026-06-06

### *---- "Fraud"
Has anyone tried taking the ring off your finger and taking BP measurements or heart rate measurements? Try it! (just keep the ring within a couple of inches from your phone) It gives you the same measurements whether you're wearing it or not! This ring is bs! I had the ring 2 and now the MAX. I was supposed to get a 50% refund upon trade in. Months later I'm still waiting. I really want to like and believe it. I don't and I can't. I'm not sure about all these positive reviews about the ring or customer service. I've emailed and written reviews and no response. Experiment yourselves.
*****I'm reply to the CIRCUL reply****I've tried everything. Including sleep apnea monitoring with what appears a full battery. Nothing works!!! I've even contacted customer service and gotten no reply!!!!*****
-- BIG-ALF, 2026-05-18

### **--- "Decent hardware. Bad software"
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.

### *---- "This app sucks"
Doesn’t recognize my ring half the time nor charges it half the time
-- Yvonne CB, 2026-03-08

### ****- "First week"
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.
-- DeMeulenaere, 2026-02-28

### *---- "Customer service none existent"
Good luck any issue with ring your on your own, customer service doesn’t exist. Get a temu ring they probably address your problem better then these guys
-- The angry guy, 2026-02-20

### ***-- "CIRCUL Ring 2.0"
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?
-- Honey 0919, 2026-02-02

### **--- "Nice ring. Terrible app."
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.
-- Mhold011, 2026-01-09

### **--- "Downgrade"
Last update was a downgrade in my opinion. It has lost much visibility in monitoring things indicative of sleep apnea. No longer see stopped breathing episodes or detailed oxygen saturation numbers.
-- eagledbl, 2025-12-19

### **--- "Update Removed Sp02"
Latest update and firmware removed realtime oxygen saturation.
-- Joniceguy1, 2025-12-05

### *---- "Can’t even get setup to work"
I am trying to activate my ring and can’t even get the app to allow setup. Does not bode well for the ring …
-- גנה2003, 2025-10-14

### *---- "Useless"
App stops tracking after 7 days, no data at all, resets, unbinds, app won’t collect data so it’s useless, should’ve gotten Aura
-- Nine at nine, 2025-10-14

### *---- "Not connecting"
Loved all the features of this ring however I continue to have connection issues. My last sleep record was almost 2 months ago. I’ve charged the ring, deleted & reinstalled the app.
-- jkfan1, 2024-11-20

### *---- "Connectivity issues"
Connectivity issues are really bad and can’t sync or update due to this. Really bad start for sure!
-- Pawtucketbrawler, 2024-11-12

### *---- "Not a good start"
This ring won’t stay connected and drains the battery quickly. I have to constantly put it back in the charger to try to reconnect. It’s pretty much useless.
-- Wayne Lloyd, 2024-10-18

### *---- "Not sure if it’s the app or the ring"
Didn’t even work for 3 days. 0 data being pulled now. App just acts like it’s constantly trying to reconnect. 

Pretty bad look for a new product.
-- Tech Butcher, 2024-10-10
