UniJethro Smart Ring Health & Fitness Tracker — Silver Size 10, Heart Rate & SpO2, IP68 Waterproof

The UniJethro Smart Ring is a compact, waterproof wearable that monitors heart rate, blood oxygen, blood pressure and sleep while tracking steps and workouts — all without any app subscription.

UniJethro’s Smart Ring blends a slim stainless steel-and-resin body with optical sensors and an accelerometer to deliver continuous health and activity data. Designed for everyday wear, it offers IP68 water resistance, multi-day battery life, and compatibility with iPhone and Android devices. The ring ships with a charging cable, silicone protector, and a two-year warranty so you can start tracking right away.

How accurately does this ring track heart rate, blood oxygen, and blood pressure?

The ring uses built-in optical sensors to capture pulse waveform data for heart rate, blood oxygen (SpO2) and an estimated blood pressure metric. It provides convenient trend monitoring and quick checks, ideal for lifestyle tracking and spotting deviations from your typical patterns.

• Optical sensor array for continuous and on-demand readings
• Displays heart rate, SpO2 and blood pressure estimates in the companion app
• Better suited for everyday trend monitoring than clinical diagnosis

What fitness and activity features will help during workouts?

Inside the ring, a SC7A20H accelerometer records steps, calories burned and distance, plus recognizes common activities like running, cycling and yoga. It’s designed as a lightweight fitness tracker you won’t notice while exercising but can consult afterward for session summaries.

• Step counting, calorie estimates and distance tracking
• Activity detection for running, cycling, yoga and more
• Workout history available on iPhone and Android without subscription fees

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

The Smart Ring is built for multi-day use: expect roughly 3–5 days during normal active use and up to 7–10 days in standby. The IP68 rating gives protection against sweat and brief immersion, and the stainless steel plus resin construction balances durability with a comfortable fit.

• 3–5 days typical use; 7–10 days standby
• IP68 water resistance for washing hands and splashes
• Resin and stainless steel case for scratch and wear resistance
