The Oura Ring 5 enjoys the same app experience as the Oura Ring 4, but it's so slim and sleek, it truly feels like a piece of jewelry.

Oura says the new Oura Ring 5 is the smallest smart ring in the world, and it launches with tons of new health-related app updates.

The Oura Ring 4 Ceramic boasts a new design and works with a new accessory, one of the most requested for the device: a charging case.

Oura is a leader in the smart ring space and I set out to test the new Oura Ring 4 to see if the hype, and the subscription, is worth it.

Oura Ring 4, which replaces Gen3, comes with smart sensing technology and new Automatic Activity Detection, complemented by an updated app.
