Meet your new health partner: the PAERDUO Smart Ring. Unlike bulky wristbands, this ultra-thin 6mm ring stays comfortable all day and night. Use it to track your heart rate, blood oxygen, and sleep stages without a monthly subscription. The AI sleep analysis distinguishes between deep, light, and REM sleep, helping you understand your rest quality.
For women, the period prediction feature learns your cycle and forecasts ovulation windows. The ring's 5ATM waterproof rating means you can wear it in the pool or shower without worry. Gesture control lets you take photos or switch music with a flick of your hand. With up to 5 days of battery life, you focus on your day, not charging. No subscriptions, no hidden fees—just your data, always accessible.
