Reveri: Self-hypnosis is a free app available for iPhone users that allows you to hypnotize yourself to relieve pain and stress, improve your sleep, and build better habits. This app is a self-hypnosis tool created by Dr. David Spiegel, Associate Chair of Psychiatry at Stanford University School of Medicine, who has taught more than 7,000 people how to better manage their minds and bodies using hypnosis. Reveri offers focused self-hypnosis sessions that cover a range of challenges like insomnia, stress, focus, pain perception, eating habits, and quitting smoking.

In simple terms, self-hypnosis is a naturally occurring state of highly focused attention that can help you alter the relationship between your mind and body. Reveri membership offers access to the complete Reveri experience, self-hypnosis sessions, and short sessions that can be used frequently to help build the concentration muscle. However, it's important to note that nothing in the Reveri app should be considered medical advice. Users seeking medical advice should consult with their doctor or other medical professionals.
