One thing I miss about living on the East Coast of the states was being able to leave my windows open at night and wake to the comforting sound of a soft rainstorm. I love that this app lets you choose from tons of different very realistic and specific sounds to make your own perfectly tranquil mix. It really helps me to relax and sleep and is very soothing if I should wake in the night. I also appreciate that it has a shut off timer.
