Smart Activity and Sleep Tracker Ring

You slip the ring on in the morning and forget it is there, while it quietly counts your steps and your sleep

It looks like a plain wide band, black, rose gold, or silver, with a smooth polished outside and a ring of small optical sensors on the inside that rest against your finger. There is no screen and nothing to check on the ring itself; at about 3 grams it disappears on the hand.

Everything shows up in the companion app on iOS or Android over Bluetooth. The Health screen lays out your steps, distance, and calories, your sleep hours, your heart rate, and blood oxygen, with activity modes for walking, running, cycling, and hiking. The app also shows an estimated blood pressure reading for personal reference. A 20 mAh battery sits inside, and a magnetic cable snaps on to charge it; a charging case is offered as a separate option.

Why It Works

A ring sits close to the pulse and stays on through the night, so it catches sleep without the bulk of a watch. The sensors do the reading and the phone does the display, which keeps the ring small and the battery tiny. Choose your finger size from 7 to 13 and your finish, then let it run in the background.

How It Fits Your Routine

Wear it to bed and check your sleep hours over coffee the next morning in the app.

How do I choose a size? Ring sizes run from 7 to 13. Pick the size that matches a ring you already wear on that finger.
