Does the Spire Stone monitor heart rate?

The Spire Stone was explicitly built to capture breathing patterns and does not sense heart rate. However, the Spire Stone is perfectly suited for monitoring, measuring and more importantly maintaining awareness of your state of mind. Spire focuses on breathing patterns for several reasons:

  • Respiration is an information-dense data stream: it has many components to it such as rate, depth, the inhalation-to-exhalation ratio (IER), durations of inhalation, retention, exhalation, and hold, consistency, smoothness, transition, and so on.

  • Better breathing is easy to apply in our lives. It's useful all the time and can be done without special activity. Feedback about our breathing can strengthen our innate awareness of our own breath to help us become more self-aware and effective at work and in life.

  • We have all taken a deep breath when we were worried - and have felt the effects. Spire helps remind you to take such a breath, especially when you are stressed.


At Spire, we understand heart rate, respiratory sinus arrhythmia (RSA), heart rate variability (HRV), skin conductance, body temperature, and pupil dilation are rich sources of information about your body and state of mind. Based on this understanding, data science, engineering R&D and customer feedback, we continue to innovate new products with the end goal of helping our customers to discover calm and improve performance.
