HeartBond Local is a unique and highly innovative app that measures how well your heart rate patterns synchronise with those of another person. Higher levels of synchronisation have been shown to be indicators of happier and better bonded relationships. The app measures the hearts of two people in real-time, analyses the heart rate patterns and displays a score to show you how well two people are connecting/bonding. The app requires two Bluetooth heart rate monitors such as the HeartMath Inner Balance or Polar H7 or H10 chestbands. The app will function out to a maximum Bluetooth range, which can be about 10 metres or closer if through a thin wall. HeartBond is in an experimental phase of development and we invite users to offer their feedback so we can improve it and make the world a more connected, happier and loving place.
