Umpteen trackers exist to quantify various elements of your lifestyle: steps taken, sleep quality, posture, and the like. But by far the most interesting in recent memory is Spire. Clip this soft, stone-like device to your belt (or bra) and it instantly starts analyzing your breathing patterns in real time, giving deeper insights into your various states of mind, for instance whether you’re focused, calm or tense. If you seem stressed, Spire attempts to pull you out of it by pushing notifications to your smartphone, discouraging shallow breathing by making you focus and concentrate on taking deeper ones. And when its 7-day battery runs out, drop it onto the included cork-lined Qi charging pad for a quick top-up.
