Spire knows when you're tense and reminds you to breathe.

This is Spire. While unobtrusively clipped to your pants or bra, Spire measures your breathing patterns throughout the day. It can notify you when you're tense, guide you to greater calm, help you discover what makes you focused, and much more.


Breathing and controlling your breath is one of the easiest ways to improve mental and physical health.


Control your breathing. Control your state of mind.

Studies have shown how simply controlling our breathing can lower blood pressure, reduce tension and increase endorphins. Spire measures respiratory patterns to detect subtle changes in your state of mind and gives you tools to achieve greater calm and focus.
