Meet 2breathe: a smart wearable device that helps you fall asleep and get proper amount of rest every night. It has guided breathing, so you will have to simply use the respiration sensor and follow real-time coaching to get in the right mood for sleep. You will be able to see the number of breaths taken and when you fell asleep on your smart device.
2breathe turns your breathing into tones to slow your breathing over time. It has already won the 2017 CES innovation award.[where to get it]
