The Mindfulness and Activity Tracker offered by Spire represents an evolutionary jump in wearable technology. This device makes a bid to track both your movements and your breath, which it uses as a proxy to determine the state of your mind. If you are breathing slowly and regularly, it records that you're relaxed. If you start hyperventilating, it'll mark you down as stressed. Go figure. At its most basic, the Spire is your typical step counter. It uses accelerometer technology to count strides. It also uses that accelerometer, to limited effect, to monitor your breathing. All this data is tracked and recorded in an associated phone app. The phone app further parses that data, mainly the breathing data, to estimate your mood and stress level.
Finally, the app can work with the breathing information to provide a sort of guided meditation. While the device itself isn't anything special, it is the specialized data processing and inspiration that the app provides that sets it apart. Execution isn't perfect, but the idea is great and the function sound enough to earn our Top Pick award alongside the also quite specialized Bellabeat Leaf and the super-simple CSX Simple Walking 3D.
