Ultrahuman's smart rings: models, features and its US availability.
Guide
Oura Ring 5 is the smallest and newest but charges a membership. The Galaxy Ring is the cheapest and works only with Android. The Ultrahuman Ring Pro is rated to last longest between charges. Specs, prices and two-year costs side by side.
Guide
Six rings chosen on published specs, prices and subscription costs: Oura Ring 5, Samsung Galaxy Ring, Ultrahuman Ring Pro, RingConn Gen 3 and Gen 2 Air, and Circular Ring 2. What each does best, what it costs over time and who it suits.
Guide
Smart ring makers use their own sizes, so your jewelry size is only a starting point. Order the brand's free sizing kit, wear the sizer for a day and a night, and pick the smaller size if you're torn.
Guide
Ultrahuman's third-generation ring costs $479 with its charging case, is rated for up to 15 days per charge and needs no subscription. It's back on sale in the US, and Oura sued on Oct. 22 to stop that.
Wearables
The new lawsuit relies on two patents the redesigned ring was never cleared against, one of them issued two days before Oura filed. Ultrahuman says the Ring Pro stays on sale.
