UniJethro Smart Ring Health Tracker — Silver Size 11, Heart Rate & SpO2, IP68 Waterproof

The UniJethro Smart Ring is a compact, wearable health and activity tracker that monitors heart rate, blood oxygen, blood pressure, sleep, and daily movement in a stylish silver ring.

Designed to combine subtle jewelry style with continuous biometric sensing, the UniJethro Smart Ring gives an at-a-glance view of daily activity and overnight recovery without a bulky wrist device. It pairs with iPhone and Android devices via the included app (no subscription fee) and is built for everyday wear with an IP68 waterproof rating and a durable resin plus stainless-steel construction.

How accurate is the UniJethro Smart Ring for everyday health signals?

The ring uses optical sensors and an SC7A20H accelerometer to collect heart rate, SpO2 (blood oxygen), and blood pressure estimates along with motion data for steps and activity types. While it delivers continuous trends and useful comparisons over time, it’s intended for lifestyle tracking rather than clinical diagnostics.

• Optical sensors measure pulse, SpO2, and blood pressure estimates.
• SC7A20H accelerometer tracks steps, distance, and activity types.
• Automatic sleep staging gives overnight duration and sleep pattern trends.
• Data syncs to iPhone and Android via the included app without subscription fees.

How long does the battery last and how durable is the ring?

Battery life varies with use: expect about 3–5 days during regular active tracking and up to 7–10 days in standby. The IP68 rating protects the ring from sweat and short water exposure, making it suitable for everyday wear and handwashing.

• Typical use: 3–5 days per charge; standby up to 7–10 days.
• IP68 protection against dust and temporary water immersion.
• Resin and stainless-steel case balances comfort and toughness.
• Included charging cable and silicone protector simplify daily care.

What features help during workouts and daily life?
