Health Monitoring Smart Ring IP68 Waterproof – Yesido IO33

The Yesido IO33 is a smart ring that tracks your heart rate, blood oxygen and activity around the clock without putting a screen on your wrist. That is the whole appeal: it looks like jewellery, weighs almost nothing, and you forget you are wearing it — which is why people actually keep it on overnight and get real sleep and resting-heart-rate data instead of a half-empty chart.

Features

• 24-hour continuous health monitoring — tracks through the day and overnight rather than only when you remember to check.
• Heart rate tracking — a VcareVC30F-S optical sensor reading continuously.
• Blood oxygen (SpO2) — measures blood oxygen saturation, most useful alongside overnight data.
• Activity and sports tracking — a STK8321 3D motion sensor logging movement and workouts.
• Handheld camera control — trigger your phone's shutter from the ring for photos and group shots.
• IP68 waterproof — rated for water immersion, so you keep it on through handwashing, showers and swimming.
• No screen to charge nightly — a ring-sized battery paired with a 200mAh charging case, so it tops up between wears.
• Stainless steel and resin build — a finish that reads as a ring rather than a gadget.

Sizing
