Bellabeat Leaf has been designed specifically for women. Its elegant and fashion-forward look, in combination with its ability to be worn as a bracelet, a necklace or a clip, makes it a great accessory for any style. In addition to activity and sleep tracking, the Leaf also focuses on the vital part of women's health - menstrual cycle. Based on your average cycle length and the date of your last period, the Leaf app is able to determine fertile days, ovulation, period days, and can help you to track the use of contraceptives. The Leaf also helps you focus on your mental well-being by encouraging you to learn and practice deep breathing technique through guided meditation exercises found in the Leaf app. Controlled breathing not only keeps your mind and body functioning at their best, it can also lower blood pressure, promote feelings of calm and relaxation, and help you de-stress.
