Smart Ring – No Subscription Sleep, Heart Rate & SpO2 Tracker with Wireless Charging Case

All the insights of a premium smart ring — without the monthly fee. Popular rings charge $5.99/month to see your own data. This one doesn't. Pay once, and your sleep, heart rate and activity stats are yours for good.

Why you'll love it

• No subscription, ever – full access to every feature in the free companion app (iOS & Android).

• Heart rate & SpO2 – dual-sensor, all-day heart rate and blood-oxygen readings.
• Skin temperature – follow overnight temperature trends, plus cycle tracking reminders.
• Activity & workouts – steps, calories, distance and multi-sport modes (walking, running, cycling, swimming).
• 5ATM waterproof – wear it in the shower, at the pool or in the sea.
• 5–7 day battery – drop it in the wireless charging case and go.
• Built for 24/7 wear – about 3.6 g, CNC-polished metal shell with a smooth, hypoallergenic resin inner lining.

Smart reminders

Sedentary alerts, drink-water reminders and phone notifications keep you on track, without a bulky watch on your wrist.

Finding your size

Sizes 7–14 (US). Smart rings fit slightly snugger than regular rings, so if you're between sizes, choose the larger one. To measure: wrap a strip of paper around the base of the finger you'll wear it on, mark where it overlaps, and measure the length in mm.
