I recommend this app to just about every person who walks into my clinic: "Simply Being" by Meditation Oasis. I have seen this app truly transform people's confidence in their meditating abilities while reducing life-changing amounts of stress and anxiety in the process. What I love about this gentle and encouraging guided meditation app is that you can customize your meditation experience. If you need to reset your internal stress response in the middle of a busy day, choose the 5 min option. If you are having trouble falling asleep at night, choose 20 min and dose off with a deeply relaxed and quieted mind. Enjoy!
