Breathe Sync

Breathe Sync

An app that aims to help you breathe better by syncing your breath with your heart rate. 

It monitors your pulse using your phone's camera to calculate the optimum breath cycle to match the rhythm of your heart. Breathing in this way is believed to reduce stress, enhance focus and aid with relaxation.
