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

Looking for a health and fitness tracker that doesn't require you to wear a big, bulky watch? You can grab an Oura Ring 4 for just $249 from Amazon, a $100 break from the normal price. It's compatible with both iOS and Android apps, has a battery that last for days, and accurately tracks a ton of health data, from hiking and sleeping to period predictions and food intake.

This generation of Oura smart ring has a number of major improvements, but the biggest upgrade is to the overall wearability. The sensors have been recessed further into the body of the ring itself, which reduces the overall thickness considerably, and allowing for a wider available range of ring sizes. They also cover a wider portion of the ring, so there's no need to keep it oriented in one specific direction to get proper readings.

The battery life has improved a lot as well. The older Oura 3 could run for around three days before it needed a charge, where our reviewer Adrienne So reported that the Ring 4 tracked a full weekend of hiking and physical activity, as well as a music festival, and still had enough juice for at least a couple more days.

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

The Oura Ring 4 is an impressive health and fitness tracker in a surprisingly small package, and one of the only downsides from our review was the price point for the silver colored finishes. Thankfully, the mirrored silver and classic black are marked down to the lower $249 price point, with varying discounts on the other options, like $299 for the brushed silver, or a larger $150 discount to bring the gold down to just $349.
