A new subscription-free smart ring has hit the market, and unlike the Oura ring, it doesn’t require a subscription. The Luna Ring 2.0 even costs less up front: It starts at $300 (or $349 with the charging case), around $50 cheaper than both Oura and Ultrahuman.
The Luna ring is made by Noise, an India-based wearables company. The Luna 2.0 is the first version of the ring that’s available in the U.S., in case you wondered whether you missed out on an entire previous ring. Noise teased the ring at CES in January, but it’s finally hitting the market for real.
According to the spec sheet, the Luna ring and its app will track sleep, heart rate, and blood oxygen, auto-detect walking and running, and provide an AI coach. Like the Ultrahuman device, it will also provide caffeine window reminders. The comparison chart on the product page lists the software as “free” in contrast to Oura’s $5.99/month subscription and Ultrahuman’s “paywall restricted features” (Ultrahuman offers add-ons for a fee), suggesting Noise also doesn’t intend to offer a premium subscription tier. (I’ve put together a full cost comparison between the Oura Ring and the Ultrahuman if you’re curious, but suffice it to say, the Luna should be cheaper than both.)
That said, Noise’s comparison chart seems a bit off to me—it lists Ultrahuman and Oura as both having the same battery life and charge time, but I found those two to be significantly different, with Oura having a longer battery life and shorter charge time. It will be interesting to see whether Luna sticks to its promises of “4-7 days” battery life and “120 minutes” charge time. Those stats would put it roughly on par with Ultrahuman.
What do you think so far?
So far, Luna seems like an adequate Oura clone, minus the monthly subscription fee. It also has one feature that neither of its two biggest competitors offers: a charging case. According to the company, the Luna ring’s charging case offers 30 days worth of battery life. If you ask me, being able to bring a case along in your gym bag or on a trip is a game changer, as I always take off my smart ring when I’m lifting weights, and I’d love a place to put it. If it also tops up the battery, all the better.
