The Bellabeat Leaf is described as “smart jewelry” which, like many activity trackers on the market, is designed to track your daily step counts, your sleep, and your calories burned! But what sets it apart from other health trackers is when paired with the app using Bluetooth, it also tracks menstruation and ovulation and offers guided breathing exercises to reduce stress. Most fitness trackers out there are ugly and bulky. Bellabeat Leaf, with its sleek and elegant design, fits perfectly in with both my wardrobe and my style. The LEAF is made of sustainable wood and hypoallergenic stainless steel, and its sophisticated design makes it look like a stylish piece of jewelry than a standard tracker from a company like Jawbone, Nike, or Fitbit. Bellabeat Leaf can be worn on your wrist as a bracelet, as a necklace or even clipped onto your clothes like a broach.
