Oura Ring 4 ($226, originally $349)

Even if you don’t have one, you’re undoubtedly familiar with the Oura Ring’s capabilities. Running on up to eight days of battery life, it tracks over 50 health metrics including sleep, heart health, stress, and activity. Other bonuses you might’ve not known about? You can pay with your HSA or FSA, and the first month of membership is included with your purchase (with the subscription costing $5.99 per month thereafter). Read our Oura Ring 3 review for more details, though it’s based on a slightly younger model.

Editor Quote: “This product is best for people who want access to their own health data. The ring also tracks patterns over time, so you get a good sense of your typical heart rate, calorie burn, and sleep patterns. If you want to make a change, it becomes that much easier to pinpoint the problem with the Oura Ring. If you’re already an active person or want to become more active, this is a high-quality tracker.” — India Yaffe, former associate shopping editor
