Does the ring work with your phone?
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.

What this catalogue covers
Health-tracking smart rings sold new in the US with their included charger. Payment-only rings, NFC rings, fitness bands, smartwatches and measured accuracy, sleep or battery rankings are outside this catalogue.
Specifications come from the linked manufacturer documents and seller listings. We have not independently tested these products.
Before you choose.
What does the app show without a paid plan?
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.
How long does it run on your size, and where can you wear it?
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.
