UniJethro Smart Ring Health Tracker for Women & Men — Silver (Size 7), Heart Rate & SpO2, IP68

UniJethro Smart Ring is a compact, everyday wearable that tracks heart rate, blood oxygen, blood pressure indicators, sleep stages, and activity metrics without a subscription fee.

This slim silver ring combines a stainless steel and resin case with optical sensors and an accelerometer to gather continuous health and activity data you can view on iPhone or Android. Designed for all-day comfort and IP68 water resistance, the ring pairs with a companion app (no recurring charges) to display trends, enable remote photo capture, and share selected metrics with friends or family.

How does the UniJethro ring monitor my daily activity?

The ring uses an SC7A20H accelerometer plus optical sensors to record steps, distance, calories, and activity types like running, cycling, and yoga. Data syncs to the companion app where you can review daily totals and trends over time.

• Step count, distance, and calorie estimates from motion data
• Activity recognition for common workouts
• Automatic logging and sync to iPhone/Android

What kinds of health metrics will I see, and are they reliable?

The ring measures heart rate, blood oxygen (SpO2), and blood-pressure-related readings using optical sensors and algorithms, plus sleep staging for light, deep, and restful periods. These readings provide useful personal trends and alerts, but they are intended for lifestyle monitoring, not medical diagnosis.

• Continuous heart-rate trends and resting values
• SpO2 estimates and sleep quality analysis
• Blood-pressure indicator readings for trend tracking

How long does the battery last and is it waterproof?

With typical daily use, expect about 3–5 days between charges and up to 7–10 days in standby. The IP68 rating protects the ring from sweat and water immersion, so it can stay on while washing hands and during light water exposure.

• 3–5 days normal use; 7–10 days standby
• Includes dedicated charging cable and silicone protector
• IP68 waterproofing suitable for hand washing and rain

What extra features does the app and ring include?

The companion app has no subscription fees and adds convenience features like remote camera control and secure health-data sharing with chosen contacts. Purchase includes a ring, charger, quick-start guide, and a silicone protector for an out-of-the-box experience.

• Remote shooting control for group photos
• Shareable health-data mode for family or friends
• Two-year warranty and customer support

Who is this for: The UniJethro Smart Ring suits anyone seeking a low-profile wearable that blends daily health and activity tracking with a jewelry-like design. It appeals to runners, commuters, couples who share data, and anyone who prefers a ring to a wrist device and wants straightforward metrics without subscription fees.
