What is Google Breath? innovation? Quite simply, it’s a new wearable health monitoring device that measures the rate at which you breathe. The app requires a picture of your bust, but it does more than that. It also measures your heart rate, respiratory rate, and blood flow. Google uses a method called photoplethysmography to measure your breathing rate, and they plan to publish the findings in a peer-reviewed paper later this year.
