The Oura Ring 4 Is $100 Off Ahead of Black Friday

looking for a The health and fitness tracker that doesn’t require you to wear a big, bulky watch? You can buy the Ora Ring 4 from Amazon for just $249, which is $100 less than the usual price. It’s compatible with both iOS and Android apps, has a battery that lasts for days, and accurately tracks a ton of health data, from hiking and sleep to period predictions and food intake.

There are several big improvements in this generation of the Oura smart ring, but the biggest upgrade is in overall wearability. The sensors are hidden deep into the body of the ring itself, significantly reducing overall thickness and allowing the widest available range of ring sizes. They also cover a large portion of the ring, so there is no need to keep it oriented in a specific direction to get a proper reading.

Battery life has also improved significantly. While the older Oura 3 could go for about three days before needing a charge, our reviewer, Adrienne So, reported that the Ring 4 tracked an entire weekend of hiking and physical activity, as well as a music festival, and still had enough juice for at least a few more days.

You get a ton of health and physical fitness data from the Ring, neatly sorted into daily physical data, detailed vitals information and longer trends over time, all organized in an app on your phone. If you want to keep track of your food intake too, a new food feature lets you take photos of what you eat and then track its effects on your body. Oura has also teamed up with Natural Cycles, a fertility tracking app, to predict menstruation using your basal body temperature.

The Oura Ring 4 is an impressive health and fitness tracker in a surprisingly small package, and the only downside in our review was the price point for the silver-colored finish. Thankfully, Mirror Silver and Classic Black are marked down to a lower $249 price point, with varying discounts on other options, like $299 for brushed silver, or a huge $150 discount to bring the gold down to just $349.
