I got this smart ring to help stay on top of my fitness goals and keep an eye on my sleep cycles—and it’s doing exactly that. Tracks heart rate, blood oxygen, steps, and more without needing a monthly subscription. The fit is comfortable, it syncs easily with my phone, and it’s super convenient to wear all day and night. Solid option if you want something low-profile but packed with features!

Incorrect data gathering. I haven’t slept for >8 hours, and I woke up in between twice for over 2 hours….but the App recorded, I had a good night sleep👎🏼 Walking steps counting not accurate, it counted when my hands were waving when I was sitting or standing still.😂 Blood pressure and heart rate are not automatically tracking, need to click at the App to get measuring….., There’s useless wearing the ring for daily base. The App is not safe to be downloaded, requires user’s location….., otherwise, it won’t work.

Location and contact list) that is then provided to account servers located in China. Failure to provide this data results in non-functionality of software and by extension the device.
