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.

Notifications & insights for a more calm and focused day.

The included app for iOS:

  • Notifies you when you're tense or haven't taken a deep breath.
  • Maps your state of mind throughout the day.
  • Guides you to a more calm or focused state.

Take a deep breath and relax. Behind that common piece of advice is a complex series of physiological processes that calm the body, slow the heart and help control pain.

Spire is so tuned into me and my body, it even lets me know if I'm tense and could use a quick 2 minute meditation boost. ... Spire is amazing. Its like a personal buddy at your side, helping you be your best each day.

Spire is the first wearable that actually measure something relevant to my wellbeing rather than just my activity. So, major props to the Spire folks. The design is simple and elegant. No buttons or switches.
