Wearing Guide

01

Choose The Right Finger

  • Best worn on your index or middle finger
  • Avoid the pinky or thumb for optimal sensor accuracy
  • Use your non-dominant hand for better consistency and comfort
02

Ensure a Snug, Comfortable Fit

  • Ring should fit securely but not tightly
  • It should slide over your knuckle with a gentle twist
  • Not too loose — it shouldn’t spin or slide off easily
03

Wear it 24/7 for Best Results

  • LYF Ring is designed for day and night use, including sleep
  • It’s waterproof — so safe for showers, workouts, and handwashing
  • The more consistently you wear it, the more accurate your insights

Keep Sensors Facing Palm Side
