Smart Rings

We wore every major smart ring to bed for weeks. Six earned a place on your finger, and one is the easy pick for most people.

Samsung's first smart ring nails the hardware and the charging case. Whether it's worth $399 depends almost entirely on the phone in your pocket.

The lightest ring we tested and the deepest metabolic data outside a lab. The battery is the asterisk you need to read.

Nearly double the battery of the flagships, no monthly fee, and the only FDA-cleared sleep apnea screening on a ring. The catch is minor.

A genuinely medical feature no other ring offers, wrapped in an app that kept crashing on us. Thrilling and frustrating in equal measure.

The world's first luxury smart ring. Judge it as tech and it's absurd. Judge it as fine jewelry that tracks your sleep and it adds up.

The budget ring we hand people without a single caveat. It gives up one feature and almost nothing else.

Dependable, affordable, and quietly capable. Just check the sizing chart before you get attached.

It doesn't win a single category, and for plenty of buyers, doing everything well for no monthly fee is exactly enough.

Cycle tracking at the core, an open-band that flexes with your finger, and a real point of view. Buy it with the warranty in mind.

Not accurate enough to make health decisions on, but the cheapest way to find out if the ring form factor is for you.

You don't need to spend $400 to track your sleep. These budget smart rings deliver most of the flagship experience for a lot less.

Long-term battery behavior, sleep accuracy against a lab watch, and whether the subscription earns its keep.
