The included smartphone app can guide you in short, simple exercises or mini-meditations to increase focus, calm and productivity.
Clip the Spire stone unobtrusively onto your pants or bra to track steps, calories and respiratory patterns.
Incorporates wireless charging, up to 7-days of battery life and thoughtful washer-proof design.
NOTE: Spire measures breathing to give you insight into your state of mind. It is not a mood tracker or medical device.
