Oura made the Oura Ring 4 official this week, with better battery life, new designs, and improved accuracy. But for once, you don't need the latest model to get all the new features — as these are rolling out to all Oura wearers.
So, if you're looking to pick up one of the best smart rings, now is a great time to buy the Oura Ring Gen 3 which is currently up to 22% off at Amazon with this early Prime Day deal. But don't hang about — Oura has discontinued this model, so once retailers like Amazon are sold out, it won't be coming back in stock.
It's also your last chance to invest in the flat-topped Heritage edition, as the Oura Ring 4 only is only available in the new fully circular, all-titanium design. The discount varies between Horizon and Heritage, and by color, but you could save up to $100 depending on your preferred configuration.
Alongside the new ring, Oura announced a redesigned companion app for Android and iPhone, making it easier to spot short and long-term trends, with three new features; Automatic Activity Detection, Fertility Insights and Daytime Stress.
These aren't limited to owners of the latest Ring 4, as anyone with a Gen 3 ring will also be able to use them, so long as you take out Oura's subscription for $5.99 per month. The main difference is that the data informing Oura's analysis should be more accurate on the Ring 4.
That doesn't mean that the Oura Ring Gen 3 isn't worth the money though. The company goes to great lengths to test the accuracy of its data with studies and research, and the real-world performance bears that out.
The Gen 3 ring spotted that our fitness editor was pregnant before she did, and helped one of our team find out that they experienced sleep apnea. However, Oura's suggestion that the battery lasts seven days seems more like five in practice.
If you're hoping to squeeze in more time between charges, the new Oura Ring 4 has a quoted eight-day battery life. Plus, the sensors are now recessed into the ring, which might improved comfort compared to the Gen 3 with its sensor bump.
And Oura didn't increase the price on the Ring 4. The Gen 3 started at $299 for the base Heritage version, while the cheapest circular Horizon cost $349. Meanwhile, the circular Ring 4 starts at $349, so there's no price increase between models.
