The ring is IP68 waterproof, so you can wear it while swimming, running, or in the rain. It comes with a portable charging case that provides multiple charges, giving you up to 5 days of use per full charge.
Pair it with your iPhone or Android phone via the free app to view trends and adjust your habits. The gesture control lets you take photos hands-free—a handy feature when you're working out. With comfortable, lightweight design and multiple size options, this ring makes a thoughtful gift for anyone focused on their wellness journey.
