IŌNE App
Your Daily Score
Every morning, IŌNE gives you a single number — from 0 to 100 — that tells you exactly how your body is doing. Based on your sleep, recovery, heart data and activity, your daily readiness score tells you whether to push hard or take it easy. No guessing. Just clarity.
What IŌNE Tracks
Heart Rate Continuous monitoring throughout the day and night. Know your resting rate, your peaks, and everything in between.
Blood Oxygen (SpO2) Track your oxygen saturation levels in real time. A key indicator of how well your body is recovering and functioning.
HRV — Heart Rate Variability One of the most powerful indicators of stress and recovery. IŌNE measures it in milliseconds so you always know where you stand.
Skin Temperature Monitor subtle fluctuations in your body temperature — a reliable signal of fatigue, illness, or hormonal changes.
Stress Level A continuous pressure score keeps you aware of your body's stress response throughout the day.
Sleep
IŌNE tracks every stage of your night — deep sleep, light sleep, and movement — and gives you a sleep score out of 100 each morning. See exactly how long you spent in each phase and get personalized insights to improve your rest night after night.

For Her
IŌNE goes beyond fitness. For women, the ring tracks menstrual cycle patterns, monitors skin temperature fluctuations linked to hormonal changes, and helps you understand how your cycle affects your sleep, energy and recovery — day by day. Because your body deserves to be understood at every stage.

One Ring. Total Awareness.
From the moment you wake up to the moment you fall asleep, IŌNE is quietly working — reading your body, learning your patterns, and turning raw data into insights you can actually use. No screen on your finger. No charging every night. Just intelligence, worn.
