How It Works

Wear — Slip the ring on like any band. IŌNE fits comfortably day and night, designed for sizes 7–12. Titanium frame with ceramic coating: lightweight, hypoallergenic, scratch-resistant. No charging cables to fumble with — it stays ready when you are.

Connect — Pair instantly with the app via Bluetooth. One tap links the ring to your phone and your data syncs automatically in the background — no complex setup, no accounts to manage, no distractions.

Track — Sleep, heart rate, blood oxygen (SpO2), HRV, stress levels, activity and calories. IŌNE reads your body's signals 24/7 using advanced PPG sensors and a built-in accelerometer, all packed into a 2.5 mm slim ring — no screen on your finger required.

Understand — Open the app to see your trends. Personalized scores show how well you slept, how ready you are to train, and where to recover. IŌNE learns your patterns over time and delivers precise insights, day after day. Intelligence you can truly act on.

Live — Wear it and forget it. Up to 5–7 days of battery life, full magnetic charge in 60 minutes, IP68 waterproof rated to 50 metres. A design that disappears into your life — in the pool, at the gym, in your sleep.
