Then once you wear it and find out the ring doesn’t work, they tell you that they do not give returns after 14 days and the ring has to be unworn. I didn’t even get 2 weeks out of this garbage I spent $500+ on. DO NOT BUY THIS OR YOU WILL REGRET IT. LOOK UP THE CIRCULAR RING GROUPS ON FACEBOOK… THOUSANDS OF PEOPLE COMPLAINING ABOUT THEIR CIRCULAR RINGS NOT WORKING. JUST DONT… ### 1/5 — Insupportable ! App trop bugé, pertes de données récurrentes *2026-07-26, version 29.16.1* En 3 mois c’est-à-dire 5 ieme fois que l’app crash lors de la synchronisation bague app. Les données stockés sont toutes perdues. Faut revoir le code de votre app c’est n’importe quoi Et je ne parle meme pas du manque de fiabilité des données notamment cardio, lorsque je compare avec ma montre garmin j’ai toujours des énormes différences ### 1/5 — Lack of Technical attention *2026-07-26, version 29.16.1* Since I purchased the ring, it only registered sleep data one night, and due to calibration process. Despite of my continued requests p for technical attention, and after sending them all the data they requested, no technical support was received, and the ring is yet defective: if the sleep data are missing, many of the features won’t function, either. I have sent them about 20 email and messages, and yet, no solution given. Caveat empor. ### 1/5 — Still complete rubbish *2026-07-26, version 29.16.1* Absolutely appalling product and disgraceful customer service. The Circular app is complete rubbish, the ring itself is unreliable, and the customer service is virtually non-existent. It took six months just to receive a response, followed by another three months of endless back-and-forth, with no proper resolution. Despite the ring clearly being faulty, Circular has refused to replace it. Instead, they repeatedly ask for the same information and data that has already been submitted multiple times. It feels like a deliberate attempt to delay, frustrate customers, and avoid taking responsibility for a defective product. The health and sleep metrics are wildly inaccurate, the ring constantly disconnects and reconnects, and the connection issues make the app almost unusable. Trying to track a workout or sporting session is an absolute joke. Most of the time, it either fails completely or produces data that cannot be trusted. This is easily one of the worst products I have ever purchased and one of the worst customer service experiences I have ever had. Circular should be ashamed of the way it treats paying customers. Do not waste your money. Do not trust the metrics. Do not expect support when something goes wrong. Avoid Circular at all costs. BUY AN ULTRAHUMAN OR OURA. Great product and very accurate metrics. ### 1/5 — Terrible Product *2026-07-19, version 29.16.1* 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. ### 1/5 — Deceptive *2026-07-18, version 29.16.1* 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. ### 1/5 — Doesn’t work way more frequently than it does work *2026-07-17, version 29.16.1* 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. ### 1/5 — The ring is Garbage. *2026-07-17, version 29.16.1* 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. ### 5/5 — 機能充実 *2026-07-16, version 29.16.1* Kiraの分析は素晴らしい！ ### 5/5 — AIが色々教えてくれる。 *2026-07-16, version 29.14.3* 睡眠や運動、ストレスなどのデータをAIがまとめて要約して教えてくれる。 ## Frequently asked questions about Circular Ring ### What does the Circular Ring app do?
