## Features

- SIZE FIRST BEFORE YOU BUY - Ultrahuman Ring sizes are different from standard ring sizes. Purchase a Ring sizing kit first, wear it overnight, and purchase the perfect Ring AIR size for you. Ring AIR is available in 10 sizes from 5-14.
- TRYING THE SIZING RING - It is important to first use the sizing kit to determine the ring AIR size. Wear your ring sizer for at least 24 hours to know your fit. Wear the ring such that the engraved size number is toward the palm of your hand.
- FINDING THE CORRECT FINGER - For optimal comfort and advanced sleep tracking, we recommend you wear the Ultrahuman Ring AIR on your index, middle, or ring finger.
- RECOVERY SCORE - Get insights into various recovery signals your body sends throughout the day, enabling a deeper comprehension of its needs. It is derived from a blend of key metrics, including Heart Rate Variability (HRV) and Skin Temperature, interpreting the signals your body sends and enabling you to monitor your overall well-being.
- WORKOUT TRACKING - The Ultrahuman Ring AIR has a dedicated 'Workout Mode' that tracks various activities, giving you deeper insight into your overall workout metrics. By tracking heart rate during workouts, you can gain insights into your cardiovascular response, track intensity levels, and make informed decisions to improve your fitness outcomes.
