UniJethro Smart Ring Health Tracker (Black, Size 7) — Heart Rate, SpO2 & Sleep Monitor, IP68

UniJethro Smart Ring is a compact, waterproof wearable that tracks heart rate, blood oxygen, blood pressure estimates, activity and sleep without monthly app fees.

Designed to sit comfortably on your finger, this ring combines optical sensors, an accelerometer, and a stainless-resin body to monitor daily metrics and workouts while remaining discreet and durable. It pairs with iPhone and Android devices, offers remote camera control and data sharing, and includes a charging cable and silicone protector in the box. The IP68 rating makes it resistant to sweat and incidental water exposure so you can wear it through handwashing and light rain.

How accurate are the health and activity readings?

The ring uses optical sensors for continuous heart rate and blood oxygen (SpO2) sampling and an SC7A20H accelerometer for step, distance and calorie estimates. Readings are suitable for trend tracking and lifestyle adjustments but are not a substitute for clinical devices or professional medical advice.

• Continuous heart rate monitoring with on-demand checks
• SpO2 measurements to observe daily oxygen trends
• Accelerometer-based step, distance and calorie estimates
• Sleep staging and duration derived from motion and heart-rate patterns

What battery life and charging should I expect?

Battery performance depends on usage: typical daily monitoring yields about 3–5 days of use, while standby extends to around 7–10 days. The package contains a dedicated charging cable for quick top-ups; nightly charging is a convenient routine for continuous tracking.

• 3–5 days with regular health and activity monitoring
• 7–10 days in low-activity standby
• Included proprietary charging cable for easy recharges
• Silicone protector supplied to reduce wear during charging and daily use

Is this ring comfortable, durable, and suitable for workouts?

The UniJethro ring blends a stainless steel core with a resin outer case to balance strength and comfort. Its ergonomic profile is intended for all-day wear, and the IP68 rating shields electronics from sweat and short water exposure during everyday activities and many fitness sessions.
