This app is a game changer. The combo of vibration & sound is fantastic. After using it for a week on my chest I felt much more centered. The sounds were great for sleep. Also loved the ease of using Airplane Mode. No EMF + no pinging texts when I meditate.
Great addition to my meditation practice.
