I really like the brainwave app, I don’t understand about the brainwaves at first, do not believe, and began to learn through Wiki some brainwave knowledge, it is about to adjust the state of one’s mind, through the regulation of the state of the brain to achieve the role of physical and mental regulation. I like the sleep package, meditation, and chakra opening, and now my sleep quality has improved significantly and easy to meditate. I will continue to listen to chakra opening and balance my energy. Now Im in good mood every day. Thanks for letting me know this app. Thank you for your team!!!
