Great sleep and white noise tool
I dont know if its just the power of suggestion at work but the tones do seem to work on me. They work best with full headphones on but are OK with buds if the room is quiet.
I use this app to fall asleep at night sometimes. When I do, I notice the difference in how I feel in the morning. Its almost always better on the nights that I fall asleep to this app.
