Most of the time it doesn’t sync properly, and the company says it could be months before the server issues are resolved. This has been one of the most frustrating pieces of tech, and had I not got it through the Kickstarter I would have already returned it. -- Aethervale, 2025-10-05 ### **--- "Not close to oura ring" I wanted to like this as it does not have the monthly subscription fee that oura has. 3 weeks in and it does not pick up workouts does not give me the same data and gives meaningless hints as to what is going on with my body This is not a replacement and it's going into junk pile soon . -- tbna123, 2025-10-04 ### *---- "Can’t use the ring without the app but app doesn’t work" I haven’t been able to upload data in over 3 weeks. So I only had a functional product for 1 week. Hard to make it a habit when it doesn’t function. I was really excited to use it and wear it when I first got it, but I’m quickly getting conditioned to not even try. Really expensive for a bulky piece of jewelry that I don’t even like the look of. Idk what the problem is but this is unacceptable for a product that relies on an app to function. Whenever I try to sync, it looks like it will upload (72% is the farthest it’s gotten) then the whole app crashes or the upload progress just disappears. -- KNHdermii, 2025-10-02 ### ***-- "Unresolved defects & overly optimistic analysis" Putting aside some infrastructure scaling issues the Circular team is working through, I still think this app and analysis algorithm requires significant improvement compared to the Oura experience. On the UX side, every time I edit the layout of my dashboard it seems fine but doesn’t really save and eventually reverts to the default view. Sometimes not all boxes are visible - not just the ones that are dynamic like napping and sports but also things like skin temperature. Those defects need to be addressed. Beyond that, comparing it to my use of the Oura ring, I don’t feel like the analysis is accurate. For example it tells me my ideal sleep duration is 6 hours. If I sleep for that little time I feel absolutely awful. Since it insists that’s correct, it’s inflating my sleep scores when I’ve only had mediocre sleep. Something is off about the calibration methodology that the ring already completed or analysis. Don’t expect that during calibration I’m ever going to sleep well. The app should still maintain the ideal for me and adjust as needed instead of baselining at an inaccurate value. -- JG001011, 2025-10-01 ### *---- "Do not purchase!" This is the worst company I have ever dealt with. They will not respond to emails or chat. Absolutely no customer service. -- Fittech54, 2025-10-01 ### *---- "Doesn’t work - No support" It’s been 7 days since my ring was able to sync to the app. I’ve reached out to support through email, chat, online form and socials. No response. They’ve been experiencing “down time” for a week straight. They give troubleshooting steps through status page updates that do nothing. I wouldn’t recommend this company to anyone. -- iphoneappreviewsn, 2025-09-30 ### *---- "Stay Away!" Had the circular 2 ring a few weeks then it stopped syncing. No response from support. No amount of restarting ring, reinstalling app, deleting the ring or even factory resetting the ring has resolved and there is Nooooo Support. Basically this is now a 300 dollar paperweight I waited 5 months to get and only got to use for three weeks. Thieves! -- Amazing all occurs, 2025-09-30 ### ***** "Always improving" Every launch has its own kinks that need to be ironed out. I have faith in the team behind this product and can’t wait for all of the innovations. The app has been working great for me and has already given me so many insights about my health and my life. It’s very eye opening. -- AG968, 2025-09-30 ### *---- "This is terrible." I have tried to like this. I started with the first Pro ring and it died. Replacement died in a few weeks. The new ring 2 is okay but the accuracy and consistency is absolutely the worst. -- J@$0N_C, 2025-09-30 ### **--- "App won’t open" After the recent update, I can’t get more than a day or day and a half use of the app, it freezes on the loading screen/ splash page and never opens. They put out a bulletin that there’s cloud server issues, and not to delete and reinstall the app, as doing so deletes all your data. But that is the only way I can get the app to open for the last 7 days. Upon reinstall it will work for about a day and then it won’t load or open anymore. Prior to that update it worked pretty well, at least it opened consistently and sync ring data most of the time with occasional connection issues. An issue that persists prior to update and since, after any “Walking” workout is recorded, it gets stuck and cannot finalize the workout report as it says ongoing measurement in progress. I think this is more of a ring issue than app, as the green lights remain on the entire time and only way I can get it to stop and finish uploading the workout report is to put the ring on the charger. Step count is miserably inaccurate. Apple health tracking me at 12k+ steps and some days ring says I only have 600! Overall not impressed. When it works well, the rest of the data is nice. But too many glitches and issues. The ring feels like it maybe should still be in beta testing to work out a few final things, and the app is embarrassing to release something so unstable to a customer. -- bosinator, 2025-09-27 [View all Circular Ring reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Circular Ring Discovered Keywords -
