UniJethro Smart Ring Health Tracker for Women & Men — Gold 8#, Heart Rate & SpO2, IP68 Water-Resistant

UniJethro Smart Ring is a slim, all-day wearable that tracks heart rate, blood oxygen, blood pressure tendencies, activity and sleep with an IP68 water rating and multi-day battery life.

Designed to blend jewelry-style aesthetics with wearable tech, this gold UniJethro ring combines resin and stainless-steel construction with optical sensors and an SC7A20H accelerometer to deliver continuous activity and overnight sleep monitoring. It connects to iPhone and Android without subscription fees, includes a charging cable and silicone protector, and offers up to 3–5 days of normal use or longer standby when not in active use.

How accurate and useful are the ring’s health readings?

The ring uses optical sensors to sample heart rate, blood oxygen (SpO2) and blood pressure trends; it also logs sleep stages and movement patterns. While useful for spotting trends and sharing data, it’s not a medical device and should not replace professional diagnostics.

• Continuous heart-rate sampling for resting and active periods
• Spot SpO2 measurements for overnight and on-demand tracking
• Blood pressure trend estimates rather than clinical readings
• Sleep staging and interruptions detected via accelerometer

How long does the battery last, and how do I charge it?

The UniJethro ring is engineered for everyday wear with approximately 3–5 days of active use depending on sensor frequency and phone connection. When not actively sampling you can extend standby up to about 7–10 days. Charging is quick and user-friendly using the supplied dedicated cable.

• 3–5 days typical use; 7–10 days standby
• Dedicated charging cable included in the box
• Silicone ring protector for safer charging and storage
• Simple magnetic/plug charging—no extra dock required

Is the ring durable and comfortable for everyday wear?

Built with a resin and stainless-steel case and an ergonomic profile, the ring is lightweight and designed for continuous wear, including hand washing thanks to its IP68 water resistance. Multiple sizes help you find a secure fit that stays comfortable during exercise and sleep.

• Resin + stainless-steel construction for comfort and durability
• IP68 rating protects against sweat and temporary immersion
• Available in multiple sizes for an accurate fit
• Low-profile design avoids catching on clothing

What connectivity and extra features come with the ring?

The ring pairs with iPhone and Android devices via the companion app at no recurring cost, offering remote photo control and a friends sharing function for health data. The package includes customer support and a 2-year warranty to help with setup or issues.

• No app subscription fees; one-time setup with companion app
• Remote camera trigger for hands-free photos
• Health-data sharing mode to exchange reports with friends
• 2-year warranty and responsive customer service
