## What is Luna Ring?

Luna Ring is a smart ring from Lunazone that records biomarkers through the day and night; the same store sells the second-generation ring, a version bundled with a dock charger and the Luna Band. Sleep is split into stages such as deep and REM, with interruptions shown. Temperature and recovery shifts are used to estimate cycle phases, while heart rate, recovery trends and temperature changes are read as signs of stress. Daily effort is weighed against recovery to inform training load. A feature called LifeOS turns these readings into short prompts, for example to drink water, move after a long still period, take a break or wind down. The site describes the insights as AI-powered, says no subscription is charged and reports sales in more than 70 countries.
