I never expected a small wearable to change my daily wellness routine so much. It quietly tracks my heart rate, SpO2 and sleep while fitting under my ring — now I feel safer during workouts and overnight. Simple, reliable, and oddly reassuring every time I check my stats.

Common questions about the Smart Ring and health tracking

Clear answers on battery, SpO2 accuracy, warranty, and how the ring improves daily wellness

How accurate is SpO2 on the ring?

The ring uses optical sensors tuned for fingertip readings to deliver reliable SpO2 trends. It’s designed for daily monitoring and to flag meaningful drops, though not a medical diagnosis.

How long does the battery last?

Typical use lasts a full day on a single charge (15mAh models), with select models offering longer runtime. Quick top-ups keep you protected through busy schedules.

Can I wear it during workouts and showers?

Yes. The ring is built for active use and daily wear. It survives sweat and light water exposure, so you can track runs, lifts, and recovery without removing it.

Will data sync to my phone?

Yes. Health data syncs to the app for easy review. See SpO2, HRV, sleep and temperature trends and get actionable tips to improve recovery and performance.

What if I need returns or support?

We offer a 30-day return policy and responsive customer support. Contact us for warranty or guidance and we’ll help with setup, tracking, or troubleshooting.
