Do you want to know how many calories you burn while working out? How many steps you take in a normal day? How well you’re sleeping? Although most trackers do a decent job measuring each of these categories, some are specifically designed for fitness (measuring heart rate zones and split times), whereas others are designed to give you a snapshot of your normal routine (step counts and sleep quality).
Still others are meant less as fitness wearables and more as health trackers – even collecting information that can give doctors particular details about a patient’s heart health or adherence to a prescribed lifestyle. Before you think about colors and styles, make a list of exactly what you hope to learn from your tracker and then use that to narrow down your options.
