Spire, the first wearable that tracks physical movement and the wearer’s state of mind, is now available for both iOS and Android. As well as tracking the wearer’s physical activity and step goals, the small clip-on device monitors breathing patterns and vibrates when it detects persistent tension. This breaks the cycle of anxiety and reminds users to breathe deeply. The connected app provides a library of meditative exercises for relaxation and detailed reporting on the wearer’s state of mind throughout the day, steps taken and calories burned. It costs £119.95.
