ULTRAHUMANRing AIR- Sleep-Tracking, Movement & Recovery,HRV, 6 Days Battery Life with Lifetime Free Subscription (Aster Black, 8)

So far I really like. I got the Aster Black color. I would definitely recommend getting the sizing kit, the sizing app was not accurate at sizing for me. The Ultra Human app is nice, provides a lot of helpful info. I really like that there is no subscription fee. It’s lightweight and comfortable to wear. So far no complaints.

Bought it, got it, charged it, wore it, good so far x6 weeks.Pros: what they say about the ring is true. Works well, wore in shower and still all good, no subscription fees. Get and keep the prefit kit.Cons: if you get fat or skinny you will need to go up or down a size. So far, changing fingers (left, right) works in most scenarios.Takeaway: could be better, could be worse. Excellent functional tech for the average person. Recommend product.

The app extrapolates to mainly, "guess" your sleep data, useless to track S. Apnea. Can't track swimming training and battery life is poor, a hassle for travelers. It does give you heart rate and some interesting breathing exercises.

Der Ring hat etwas Zeit (~2 Wochen) gebraucht um meinen Körper kennenzulernen, aber jetzt bin ich echt begeistert!
