Ultrahuman

Sometimes there are a few issues of the app connecting to their server, and a few things I did not understand, e.g., why a workout needed to be completed before one could use VO2max rather than having VO2 available continuously, as is for sleep. That said, it seems they continuously work on improvements, and the support staff is really wonderful. It would be good to support use of app with same ring on multiple devices, and have a matching wrist device for (weights, etc.) gym workout."

Second day with the ring and app, and will update my rating / review over time. Overall, it's a good experience and the ring is shockingly light. This is a good thing. Wearing the ring on the treadmill doesn't count steps as accurate as Samsung Health for example, the step increment is much slower as I counted in real time. Also, when can we expect workout mode to hit Android?"

This is the most incredible smart ring purchase ever. The ONLY reason I bought this was because unlike stupid Oura they dont gouge you with a subscription. You buy ring and it and your data is yours as it should be! That was a great decision on Ultrahuman's part. And it is almost as good!! Only difference is there is no menstrual cycle tracking which im sure is coming. They are constantly updating and innovating and their nudges for proper sleep habits are invaluable. 10/10"
