The Luna 2.0 smart ring just made its global debut at IFA 2025, and it's taking direct aim at Oura's wallet-draining subscription model. While Oura charges $5.99 monthly on top of the $349 ring price, Luna 2.0 delivers similar health tracking without any recurring fees. The device from Noise packs fighter jet-grade titanium, AI-powered insights, and up to 30 days of battery life with its charging case.
Here's the math that should worry Oura: their ring costs $349 plus $71.88 yearly for the subscription. That's $420.88 in year one, then $71.88 every year after. Luna 2.0 costs $300-$329 once, and you're done. After three years, Oura users will have spent over $564 while Luna smart ring owners paid once and moved on.
The Luna 2.0 doesn't cut corners to hit that price point either. You get comprehensive health tracking including heart rate, blood oxygen, skin temperature, and sleep analysis. The LifeOS platform uses AI to provide workout and nutritional advice based on your biomarkers, similar to what Oura locks behind their paywall.
The Luna smart ring delivers where it counts most, battery life. While Samsung's Galaxy Ring manages about seven days, Luna 2.0 hits five days solo or up to 30 days with its portable charging case. That puts it ahead of most wearables in the market.
The 8mm wide titanium ring weighs just 3-5 grams and handles water down to 50 meters. Green and red LEDs monitor your vitals 24/7, while a 3-axis accelerometer tracks movement. It works with both iOS 14+ and Android 6+, unlike Samsung's ecosystem-locked approach.
Luna 2.0 arrives as smart rings gain serious momentum. Samsung charges $400 for their Galaxy Ring, while alternatives like the RingConn Gen 2 offer subscription-free tracking around the same $300 price point. But Luna's AI-powered LifeOS and extended battery life could give it an edge in this crowded field.
Pre-orders start at $300 from Luna's website. For anyone tired of subscription fatigue, it might just be the Oura alternative worth waiting for.
