The Bellabeat Leaf ($129) is a simple fitness tracker that impressed me in two ways. First, it's actually really pretty. Like, not just "not ugly," but genuinely stylish. Second, it tracks one of the most important aspects of health that almost no other fitness device does: menstruation. Finally, an all-day fitness tracker that's fashionable and meets women's needs. What the heck took so long? The Bellabeat Leaf is basic in some ways, with no display and no heart rate monitor, but it's unique in promoting deep breathing and meditation exercises. It's a great device if you're in the market for something simple, but other trackers are better for those who exercise quite a bit or count calories. The two I recommend most are the Fitbit Surge and the Basis Peak, our Editors' Choices. But for a simple, beautiful tracker, the Bellabeat Leaf has some appealing features.
