CIRCUL+

The app is nice; however, it would be better if I could explore the data either via a data export or a cursor, like the o2vibe app had, and if it would send all data to Apple’s Health App. Some of the data are there, but most are not. Of course, the issue could be on Apple’s end, but this shortcoming is disappointing, as the app’s ability to sync with Apple’s Health suite was a critical part of my decision to purchase the Circul+ ring. Edit: I decided to lower my rating, because the Sleep Report will give a lowest SpO2 value, but this value does not appear on the chart/graph, meaning I cannot tell *when* this dip occurred, which is critically important information (i.e., I need to be able to ascertain if the dip occurred when I got out of bed and walked around or while I was asleep).

I really wish this app would work with Apple Watch. I have to get into the app from my phone and it can be inconvenient a lot of times with my work.. :(

And poor user interface on app. I have reached out to the company twice for help to keep the device connected to anything! So far crickets. Seems the support team is as useless as the device itself. I will ask for a refund. Buyer beware this is not what you think it is. The user interface on the app is not intuitive. It clunky and difficult to navigate. I am unable to find information and instructions about how to best navigate or set up the device and what the readings actually mean. Zero customer service or response. Useless
