RENPHO Lynx Smart Ring — All-Day Sleep & Activity Tracking with 7-Day Battery

Meet the RENPHO Lynx Smart Ring, a discreet wearable designed to stay with you from dawn to dusk and beyond. By leveraging the official RENPHO Sizing Kit, you can determine the correct size before you buy, helping ensure a comfortable, secure fit that feels almost like a second skin.

Beyond fit, the Lynx captures a broad set of data to illuminate your daily patterns without demanding constant phone checks. It tracks sleep quality and duration, blood oxygen levels, heart rate, stress indicators, steps, distance, and calories burned. It also recognizes everyday activities such as walking and running, delivering insights that can inform simple lifestyle adjustments.

What you gain from the data

• Sleep: duration and wake periods to spot potential rest gaps or consistency trends.
• Vital signs: heart rate and SpO2 trends that reflect how your body responds to daily activities.
• Activity: steps, distance, and calories offer a lightweight snapshot of daily movement.

No subscription, seamless connectivity

• No ongoing fees — pair with the Renpho Health App and sync with Apple Health and Google Health Connect.
• 7-day battery life plus an included charging case for travel or long work weeks without power worries.
• 5ATM waterproof rating and a titanium exterior mean reliable daily wear during workouts, rain, or showers.

In daily life, the Lynx serves as a quiet wellness companion, providing precise data through a compact, comfortable design. It suits everyday wear and situations where a quick health snapshot matters, without asserting medical claims.

Getting started is straightforward: use the official sizing kit to determine your size, then pair with iOS or Android devices and connect to compatible health ecosystems. For best results, align the orientation indicator toward your palm during measurements and remove the ring before handling slippery substances that could affect fit or readings.

Designed to fit your lifestyle, Lynx emphasizes practicality and ease. It’s a helpful companion for travel, busy days, or relaxed evenings—offering a meaningful glance at your activity and rest without demanding more time or money.
