Ratings and reviews

terrible app. crashes every time it attempts to sync. Data is incorrect, sleep is wildly off, as are steps. The heart rhythm is useless. If the ring cost 100 dollars, this might be acceptable, but for as much as I paid, I should have just gone for a better brand. Additionally, all email to the company is unanswered. Save your money, this app (and product) are awful.

The circular ring app needs to talk to its server to process ring data. Once it does and hears back, the data is presented nicely. Edit from 5 to 2 stars, until fixed: tracking a workout requires going into sport mode. at the end of which the app takes a few minutes to generate a report it uploads to the server. I have a workout from over a week ago, that fails to finish generating. so every time I open the app I see it and it tries to get generated. meanwhile the sleep tracking doesnt work.

the app inconsistency is really frustrating. when it works its great, but when it doesn't, its useless. I didn't get full data on the app for 5 days, contacted support, magically got great data yesterday, and today it won't sync at all, just keeps spinning. 10/17/2025 - today's message is to clear the cache because there is a bug. I have done that. it still won't sync. it spins to about 75%, crashes, and when i reopen the app it tells me the last time it synced was 10/15.
