Terrible Product
It worked for less than 2 weeks and then it wouldn’t stay connected, they say the battery charges in 30 minutes and last up to 7 days that’s cap, I charged it for 30 minutes it died the next day. The information it provides is also inaccurate, and they will not let you return the ring after you use it and find out it doesn’t work. Do not buy this ring.

Deceptive
I purchased this ring during their kickstarter phase under the promise of blood pressure monitoring (the entire reason I purchased the ring) and other benefits.
To date, a year later, there is still no blood pressure monitoring and at no point has my ring properly tracked my sleep regardless of restarting the ring, syncing first thing in the morning and last thing at night, etc.
I purchased the gold ring and it’s tarnished and easily scratched as well.
I’m deeply disappointed in this ring and wouldn’t have wasted my money had I known it would be this unreliable.

Doesn’t work way more frequently than it does work
After owning this ring and using this app now for over 6 months, it still doesn’t work more often than it does. Horrendous app. Wanted to give it the benefit of the doubt but it constantly is offline or won’t sync. Absolutely useless in the truest sense of the word.
The ring is Garbage.
I received my ring Sept 2025 and have been dealing with customer service since. It did not work from day 1. It never tracked sleep or provided any analysis. Customer service has done nothing but ask for pictures of the ring and other pointless asks. They have refused to replace it or refund my money. Just endless delay tactics including rude and bullying emails. Unbelievably horrible experience.
Subsequent to my review Circular responded feigning dismay of how they have dealt with this issues including the delays of nearly a year now. They advised that I ask to escalate it to a manager. I had done this before and have tried a further 3 times since their response. Their agents/bot continue to refuse to escalate and continue to delay.
Again, horrible experience.
For comparison, I also have an Oura ring. It developed a battery issue after a little over 1 year use.
After a 5 minute chat session with an Oura agent they sent me a new ring and said I could keep the old one, which still works much better than the circular, to give to a family member of friend.
Stay away from circular.
Get an Oura.
Circular continues to refuse to escalate the matter, after many clear requests, or replace the ring despite sending developer messages asking me to contact them like this:
"Hi again, and we’re really sorry that things have continued this way for you. What you’re describing is absolutely not how we want our support or escalation process to work, and we understand how unfair it feels compared to how quickly other companies resolved similar issues. The App Store review space still isn’t somewhere we can securely review your full history or act on a refund or replacement, but we don’t want you stuck in a loop. Please contact us again through the support form on our website with a brief summary of your case, mention this updated review, and clearly state that you want a manager review. We’ll flag this internally so a senior team member can look into what went wrong with both your ring’s sleep tracking and the way your ticket was handled."
No help or meaningful response just months of ridiculous asks and delays of nearly 1 year now.
Rude, untruthful and non responsive customer “service”.
Get an Oura. They have empowered their agents to provide excellent customer service very quickly.
Asked again, multiple times through contact form and email for escalation.
Circular agents refuse to escalate and then claim it was already escalated but nobody contacted me or told me...
Another f-off from Circular customer service.

Very Buggy
I was one of the early supporters of this ring. It has been buggy and crashes all the time. I would say 75% of the days it does not sync. I have had to reset the ring every week to get it to work for a couple of days. I regret my purchase and would highly recommend you not to buy the Circular 2 ring. You will be disappointed.
