How Spire Works

We designed Spire to help you keep in sync with your mind and body by measuring your breath, all-day, and alerting you to sudden changes.


Why measure my breath?

Your breath is fuel for your body, the #1 indicator of your mindset, and in your control.

That’s why we’ve spent the last three years researching and building technology to help you live your best self.


Robust activity tracking included

Steps, calories, and reminders to move.

We believe that mindfulness and activity go hand in hand. Spire can also remind you to move to meet your goals.

Use the Spire app to track your progress and see how exercise relates to your health.


Spire measures your breath via the expansion and contraction of your torso.


The Spire app analyzes and categorizes your breathing as calm, tense, or focused.


Notifications alert you to sudden changes so that you can reset your breath.
