Spire aims to get you healthy, but its focus isn’t limited to heart rate measurements or how many steps you take in a day. Clip this little device (shown charging) to your clothing, and Spire can deduce your general state of mind: an elevated heart rate and shorter breaths indicate stress, while slower breathing and a lower heart rate signify a more peaceful state. If Spire senses symptoms of stress, it will send a reminder to your phone, offering helpful suggestions to encourage you to relax. Conversely, if Spire senses you’ve been having a lazy day, it may send texts inspiring you to get active. Consider this your personal trainer and pocket yogi, all in one.
