Ultrahuman Ring PRO Aster Black, buyer-selected size (US)
Some rings pair only with Android or with one brand of phone, and some features need a particular phone. Read the stated phone and app requirements before choosing a finish.
A membership can be required for most insights, optional for add-ons, or not offered. A free first month is a trial, not a permanent entitlement.
Battery and weight change with ring size, and makers test under their own settings. Water ratings use ATM, IP or meter figures with conditions that are not interchangeable.
