Because life is too short to wear boring jewelry ? LEAF is designed as a piece of jewelry that you can wear anytime, anywhere. And it doesn't just look pretty, it will track your activity during the day, monitor your sleep during night and wake you up gently in the morning, help you tackle the stress with the breathing exercises, remind you when to take your pill and let you know when your next period is coming. @marinaosijek wears it as a bracelet on this photo, how do you wear it?
