Ditch the uncomfortable, glowing smartwatches that disrupt your sleep. The Zephiora Smart Ring rests weightlessly on your finger, continuously measuring your body's subtle vital signs throughout the night.
Track your exact time spent in REM, Deep, and Light Sleep, monitor your blood oxygen (SpO₂) saturation levels, and review overnight heart rate variability (HRV). Wake up each morning with a comprehensive Readiness Score in the free companion app to optimize your daily energy and training.
Precision Workout Metrics for Every Active Lifestyle
Whether you're running trails, powerlifting at the gym, cycling, or swimming laps, the ring automatically records your steps, active calorie burn, distance, and heart rate exertion zones.
Seamlessly integrates with Apple Health and Google Fit with real-time GPS route mapping via your smartphone—providing clean athletic analytics without distracting notifications pulling you out of your zone.
Micro-Crystalline Ceramic Meets Polished Titanium
Engineered to feel virtually unnoticeable at just 2.9 grams and an ultra-slim 2.8 mm profile, the exterior shell is forged from diamond-polished micro-crystalline zirconium ceramic and surgical-grade stainless steel.
The interior sensor array is seamlessly sealed in medical-grade, hypoallergenic epoxy resin with a smooth comfort-bevel edge that glides over knuckles effortlessly without pinching or skin irritation.
10-Day Battery Life & 50M Deep Water Immersion
Say goodbye to daily charger anxiety. Thanks to our ultra-low-power Nordic BLE architecture, a single 45-minute charge delivers up to 10 days of continuous 24/7 biometric tracking and up to 60 days on standby.
With certified IP68 water resistance up to 50 meters, you can wear it continuously while showering, swimming in the pool, doing dishes, or diving in the ocean without ever having to take it off.
Customer Reviews
"Replaced my bulky smartwatch for sleep tracking!"
I could never fall asleep comfortably wearing a heavy Apple Watch. This ring is so lightweight I genuinely forget I have it on. The sleep stage breakdown and SpO2 tracking matched my previous watch perfectly. The companion app has zero subscription fees which is huge.
"10-day battery life is real, incredibly comfortable in bed"
I charged it on Sunday evening, and by the next Tuesday it still had 25% battery left. The matte black finish is gorgeous and hasn't picked up a single scratch after a month of heavy daily wear. Very impressed.
"Gorgeous gold finish, tracks gym workouts accurately"
I get compliments on this ring constantly at my gym. Everyone assumes it's an expensive piece of designer jewelry until I show them the biometric dashboard on my phone. The heart rate tracking during HIIT workouts is super responsive.
"Magnetic dock is super sleek, charges in 45 minutes"
The packaging and magnetic charging base feel like a $300 luxury tech product. It snaps onto the dock effortlessly and is fully charged by the time I finish showering and getting ready. Best health investment I've made this year.
"Optical sensors are fast and the inside resin is buttery smooth"
The optical sensor glows with a subtle green pulse when reading heart rate. The resin inside is completely flush with no sharp edges so it never pinches my skin when gripping weights or steering wheels. Size 10 fits true to US ring sizing.
"Got the BOGO deal - Black and Gold for him and her!"
Took advantage of the Buy 1 Get 2nd 50% Off bundle. My husband got the Black Steel and I chose Gold. We both sync with our iPhones and love comparing our morning sleep scores and daily step goals. Fantastic build quality.
"Swam in the ocean for a week, 100% waterproof"
Wore it surfing and snorkeling in Miami all week. Saltwater, chlorine, and hot showers have caused zero corrosion or sensor issues. The blue steel finish looks stunning in sunlight. Highly recommend following the size chart!
"No monthly subscription fee like other smart rings"
Other major smart ring brands charge $6/month just to see your own sleep data. Zephiora gives you complete access to all metrics right out of the box with zero recurring subscriptions. For $45 this is unbeatable value.
"Fast tracked shipping and quick customer support"
Ordered with standard USPS tracking and it arrived in 7 business days safely packaged. Reached out to support with a quick question about app pairing and they responded in under 15 minutes. A+ customer service!
