IT FEELS LIKE there are fitness trackers everywhere for you to help you stay on top of your health data, but Oura Ring stands out from the pack with its unique design. Their smart ring doesn’t just look good: It funnels 24/7 health tracking to an app that serves up daily scores on your activity,

First things first: the Oura Ring is (obviously) a ring, whereas the WHOOP is a small, flat device that you wear on a wrist band. Each connects to a respective app where you can see the data that the device gathers throughout the day.

Smartwatches aren’t for everyone. Maybe you don’t want to wear a screen-equipped gadget to bed, or you’re just after something that’s less obtrusive. Subtlety is where smart rings like the Oura Ring 4 shine, and Prime Day has knocked down its cost. It costs $296.65 ($52.35) from Amazon, which is both its best price and first significant discount.
