UniJethro Smart Ring — Health Tracker Ring with SpO2 & HR

The UniJethro Smart Ring is a compact wearable that monitors heart rate, blood oxygen, blood pressure and sleep while offering remote photo control and long battery life — no subscription required.

Small enough to wear every day, this silver UniJethro ring pairs with iPhone and Android devices to record activity and sleep patterns, share family member data, and trigger your phone camera. It combines IP68 waterproofing with a portable charging case so the ring stays charged through multiple uses without monthly app fees.

How accurate are the ring’s health measurements?

The ring uses optical sensors to estimate heart rate, SpO2 (blood oxygen) and relative blood pressure trends; it is designed for consumer wellness tracking rather than clinical diagnosis. Readings provide helpful patterns over time, especially when taken under similar conditions.

• Optical sensors for continuous heart rate monitoring
• SpO2 estimates to track nocturnal and resting oxygen levels
• Relative blood pressure tracking to observe trends, not replace medical devices
• Sleep stage detection to map rest and awakenings

What battery life and charging options does the ring offer?

A full ring charge lasts about 5–7 days depending on use. The included 300mAh portable charging case stores multiple charges, extending total availability so you can recharge the ring on the go without plugging into a wall every day.

• Ring runtime: approximately 5–7 days per full charge
• Charging case capacity: about 10–15 ring recharges
• Included USB charging cable charges the case when needed
• Compact case fits in a pocket or bag for travel convenience

Can I wear the UniJethro ring in water or during workouts?

The ring has an IP68 waterproof rating, so it’s suitable for handwashing, showering, swimming and other water exposures. A removable ring protector is included to reduce wear and protect the finish during sports and outdoor activities.

• IP68 protection for submersion and everyday water contact
• Ring protector included for impact and scratch resistance
• Comfortable enough to wear during exercise and daily routines
• Durable silver finish designed for frequent use

How does the ring connect and share data with family?

Pair the ring to your smartphone via Bluetooth using the companion health app — there are no subscription fees to view your data. The app supports adding family members as linked profiles so you can monitor multiple users’ activity and vitals from one place.

• Bluetooth pairing with iPhone and Android devices
• No recurring app subscription required for core features
• Family sharing lets you add friends or relatives for shared insights
• Remote camera control: double-shake to trigger your phone’s shutter

Who is this for? The UniJethro Smart Ring suits someone who wants a subtle, always-on wearable to track wellness trends, sleep, and activity without committing to recurring app costs. It’s ideal for commuters, frequent travelers, fitness enthusiasts who prefer minimal wrist wear, and families who want a single way to monitor multiple members’ daily health patterns. Remember it’s a consumer tracker for trend monitoring and lifestyle improvement, not a medical diagnostic tool.
