Noise Luna Ring Sizing Kit for AI Smart Ring – No Subscription, 24x7 Sleep, Activity, Readiness, Stress & Menstrual Tracking, AI Coach, High Accuracy, Health & Performance Metrics, Biohackers
Try before you buy - Our sizing has 7 dummy rings from sizes 6 to 12 which allow you to choose your right fit before you purchase the final product
Choose your finger - We recommend wearing the LunaRing on the index finger of your non-dominant hand for the best performance & accuracy. However the middle & ring finger work can work as well if you'd prefer not to wear it on your index finger
Orient the ring correctly - the sensors on the underside of the ring should ideally face the palm side of your finger. The ring should fit securely and comfortably around your finger's base
Take the gap test - Make a fist while wearing the sizing ring. If you see a gap between the top of your finger and the inside of the ring, try a smaller size
Assess for 24 hours - Your fingers naturally expand and contract, so we recommend wearing your sizing ring for atleast 24 hours and then moving to the next step
