This app helps you to fall asleep faster by trying to synchronise your breath and your heartbeat while keeping your brain focused on something. Just plug your phone to your charger, preferably in airplane mode, put it next to your bed, screen up and launch the app. Lay down, inhale while the disk is becoming bigger and exhale while the disk is shrinking. The inhale/exhale will gradualy become slower, until it reaches 6 breaths per minute after a few minutes. It may help you to fall asleep wit
