Product details

Meet the RENPHO Lynx Smart Ring

Compact yet powerful, the RENPHO Lynx Smart Ring slips onto the finger to quietly collect a range of wellness data without hindering daily life. It presents a clear picture of your day by tracking sleep quality, blood oxygen levels, stress signals, heart rate, steps, distance, and calories burned. Designed for real-world use, this ring supports your curiosity about how you move, rest, and recover, offering insights you can act on in small, meaningful ways.

What it tracks and how it helps

  • Sleep patterns and quality to help you notice trends in rest and recovery.
  • Blood oxygen levels, offering a view into nighttime breathing signals and overall wellness rhythm.
  • Stress indicators and heart rate during daily activities and workouts for awareness rather than diagnosis.
  • Steps, distance, and calories burned from everyday walks to longer runs.

Power, wearability, and everyday versatility

  • 7-day battery life with an included charging case, so power stays with you during travel and busy weeks.
  • All-day wearability with a titanium exterior and 5 ATM water resistance, built to withstand rain, sweat, or splashy moments.
  • Precision tracking enabled by a capable sensor suite, delivering reliable data for personal health checks at a glance.

Smart app experience without fees

  • No subscription fees: the Renpho Health app stays free, enabling ongoing data capture and viewing on iOS and Android.
  • Seamless integration: syncs with Apple Health and Google Health Connect for a unified health picture across devices.

Fit, care, and getting the right start

Fit is essential for accurate readings. Use the official RENPHO sizing kit before buying to find your precise size. For best readings, ensure the orientation indicator faces your palm and remove the ring when hands are wet or handling slippery substances.

What you get and compatibility

The package includes a charging case for extra power on the go and a sizing kit to confirm your fit. It supports connection with iOS and Android devices, offering flexible tracking that travels with you through daily life.
