[This review was collected as part of a promotion.] Been using the Ultrahuman Ring Air for about 4 months. Overall experience is very good, I really enjoy all the detailed info the device collects. Far more detailed, accurate and helpful than any other device like smartwatches. Battery could be better but it’s not terrible. Some features in the app require an app to be running in the background. Smart alarm in my case sometimes isn’t turned on due to app not running in the background. And the majority of time it only triggers with a fallback timing.

The ability to have a device that is lightweight, and minimalist makes me forget that I’m wearing it at all. I love how insightful the device is, been able to track sleep, heart rate patterns and caffeine intake were things I need in a device and this ring does all those factors right.

Activity monitoring: I love seeing my steps automatically tracked—even on days when I’m not consciously thinking about movement, the ring keeps me on top of my activity goals.

It’s pretty great and I haven’t thought of the Apple Watch at all since owning the ring. It’s tough and durable for working out and tracks my life accurately. Sometimes it does lose data or get disconnected while working out which can be frustrating.
