UniJethro Smart Ring Health Tracker — Gold Size 9, Continuous Heart Rate & SpO2 Monitoring, IP68 Waterproof

The UniJethro Smart Ring is a compact wearable that continuously monitors heart rate, blood oxygen, blood pressure estimates and sleep while tracking activity with an IP68 waterproof design.

Designed to blend jewelry-like styling with everyday wellness tracking, the UniJethro Smart Ring offers continuous biometric sensing and multi-sport activity recording in a slim gold finish. It syncs to iPhone and Android devices without subscription fees and includes sensors and an accelerometer to capture heart rate, SpO2, estimated blood pressure, steps, calories and sleep patterns. With a 3–5 day active battery life, an IP68 rating and multiple size options, it aims to be a low-profile alternative to wrist wearables for users who want discreet data and comfortable all-day use.

How reliable are the health measurements for daily tracking?

The ring uses an optical heart-rate sensor and a motion accelerometer to estimate heart rate, blood oxygen (SpO2) and blood pressure trends rather than clinical diagnoses. Readings are intended for pattern spotting and personal wellness insights; they help reveal changes over time but should not replace medical testing.

• Optical heart-rate sensor provides continuous pulse estimates throughout the day.
• SpO2 monitoring gives periodic blood-oxygen observations for trend awareness.
• Accelerometer-based calculations track steps, distance and activity intensity.
• Manufacturer note: data is for reference only, not a medical device.

What activity and sport tracking can I expect from the ring?

UniJethro’s ring supports more than ten sport modes and records core metrics like steps, distance and calories for each session. It is suitable for running, cycling, swimming and low-impact workouts, with automatic activity detection assisting in everyday movement logging.

• 10+ sport modes including running, cycling, swimming and yoga.
• Records steps, distance and calorie estimates using the SC7A20H accelerometer.
• IP68 water resistance for hand washing and splash-prone workouts.
• Syncs sessions to the smartphone app for trend review and sharing.

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

The integrated 20 mAh rechargeable battery supports roughly 3–5 days of typical use and up to 7–10 days on standby, depending on sensors and sync frequency. The ring is built from hypoallergenic resin and 316L stainless steel for daily wear, and the IP68 rating protects it from dust and temporary immersion.

• Approximately 3–5 days active use; up to 7–10 days standby.
• 20 mAh rechargeable battery with included charging cable in the package.
• Durable resin plus 316L stainless steel construction for comfort and longevity.
• IP68 rating guards against sweat, splashes and brief immersion.

How does the ring connect to my phone and what features are in the app?

The ring pairs with iOS (9.0+) and Android (5.0+) devices via the UniJethro app, which stores sessions, sleep records and health trends without a subscription fee. The app also offers social sharing, remote camera control and simple goal tracking to keep motivation high.

• Syncs with UniJethro app on iPhone and Android, no app fee required.
• View trends for heart rate, SpO2, sleep and activity history in the app.
• Remote photo control and health-data sharing for friends and family.
• Works with standard smartphone permissions; keeps local history for review.
