Smart Rings

Shop the Odessa smart ring collection — a genuinely affordable smart ring built for people who want real health data without a monthly bill. Every Odessa smart ring tracks heart rate, blood oxygen (SpO2), skin temperature, stress, sleep stages and daily activity, then syncs to a free companion app on iOS and Android. There's no subscription, no premium tier, and no paywall on your own numbers: buy the ring once and every feature is unlocked for good.

Unlike many premium-brand smart rings that charge hundreds up front and then bill monthly just to unlock full insights, Odessa is a smart ring no subscription required — the free app gives you complete access to your sleep, heart rate, stress and activity data from day one. It's rated 5ATM water-resistant, so it keeps working through showers, workouts and swims, and a single charge lasts up to eight days.

Beyond the tracking, Odessa is designed to be worn, not noticed: a smooth, low-profile band that sits comfortably next to a wedding ring or on its own, whether you're at your desk, at the gym, or asleep. If you're comparing options and want an affordable smart ring that doesn't compromise on the readings that matter — heart rate, sleep quality, stress, SpO2 and steps — this is the collection to start with. Every ring ships with a 30-day return window, so you can try it risk-free before deciding it's the one you'll wear every day.
