Your health, on your finger — 24/7, without the bulk of a watch.
Most people stop wearing their fitness tracker within 3 months — because it's too bulky to sleep in, too fragile for the gym, and needs charging every night.
The Smart Health Ring fixes all three. It weighs less than a paperclip, survives workouts and hand washing, and runs 3+ days on a single charge — with the included wireless charging case topping it up on the go. All your data syncs to the free JSRing app (iOS & Android). No subscription. No screen. Just data.
What It Tracks
-
Heart Rate — continuous BPM monitoring day and night, not just on demand
-
Blood Oxygen (SpO2) — monitors oxygen saturation and flags anything worth a closer look
-
Sleep Stages — deep, light, REM, and awake breakdowns every morning
-
Steps & Calories — passive activity tracking, no phone needed
Everything syncs to the free JSRing app, available on the App Store and Google Play. No subscription required.

Find Your Size — Takes 30 Seconds
Wrap a thin strip of paper around the finger you'll wear it on. Mark where it overlaps and measure in mm — that's your inner circumference. Divide by 3.14 to get your inner diameter.
