This is actually my second one of these and I've really liked the functionality it offers with being able to take my blood pressure (be sure to calibrate it first with a known accurate reading) along with heart rate and such. I know that optical glocose readings aren't very accurate, but I miss when I was still able to use that in the ectri app for helping me track my keto without breaking out a breath meter like ketoscan doing finger jabs with ketomoji or a ketosis urine test strip back before the optical glocose readings had to be removed from the app

This smart ring has become an unexpectedly powerful fitness tool. It’s small and lightweight, but it tracks a wide range of health metrics with surprising accuracy. I’ve used it for everything from treadmill sessions to outdoor runs, and it gives real. time stats that help keep me on pace. The app is intuitive, and I appreciate that it doesn’t require a subscription.

This smart ring has been a surprisingly powerful little tool for keeping tabs on my fitness and wellness. I got it mainly to track sleep and heart rate without needing to wear a bulky watch, and it does both incredibly well. The app is intuitive and doesn’t require a subscription, which is a big win. I love being able to view my workout metrics and sleep stages so easily.

I was skeptical but I’m pleasantly surprised. It does what is advertised. I bought it mainly to track my sleep. I think it’s fairly accurate. I give it 4/5 stars instead of 5/5 because I don’t particularly like the aesthetic of the app but it does its job. *UPDATE* I noticed that the ring works well in recording when my phone is near. If I leave my phone, it won't record. There's no memory I suppose.

Things I like: Comprehensive health monitoring: The ring tracks heart rate, blood pressure, blood oxygen levels, and sleep patterns, providing a holistic view of my health. Advanced sleep tracking: It accurately records sleep stages, including deep sleep, light sleep, and REM, helping me understand my sleep quality. Long battery life: With up to 10 days of battery life on a single charge, I don't have to worry about frequent recharging. Concern: Limited fitness tracking: While it monitors heart rate and steps, it lacks support for specific activities.
