Spire is a small 10mm x 35mm health tracker that clips to your pants or bra. Unlike many other fitness trackers that focus on your activity, Spire is designed to measure your breathing patterns continuously throughout the day. Spire says that studies have shown that simply controlling your breathing can lower blood pressure and reduce tension.
The Spire iOS app on iPhone and Apple Watch will notify you when you're tense and help you to become more calm and focused. It provides you with guided breathing excersizes and mini-meditations to control breathing. In addition to breathing, Spire can also track your activity. It tracks steps and calories burned, and reminds you if you've been inactive for too long. The app will use the information to figure out what your state of mind is, whether it be tense, focused, or calm.
The Spire device has a battery life of 7 days, and charges wirelessly on a charging pad with USB passthrough. It can fully charge in just 2 hours time. It's also "wash proof," meaning it can survive an accidental spin in the wash.
Spire costs $149.95, and has a 30 day money-back gaurantee.
