Wellness startup Bellabeat, which has primarily marketed its wearable health trackers to women, recently introduced Ivy, a stylish, comfortable health tracker with a long-lasting battery life, poised as a prettier version of a Fitbit. But the accompanying subscription “Coach” software supporting the new bracelet feels like it’s still in beta, which is concerning for a product aiming to offer health guidance to real-world users.

Over the past eight years, Bellabeat has established a track record of releasing wearable devices that look attractive enough to wear as everyday jewelry, like its Time smartwatch and Leaf health tracker. Ivy, launched this September, aims to be its most comprehensive product yet — tracking sleep patterns, heart rate, menstrual cycles, steps, hydration, activity, mindfulness and more.
