Gro Health gave me the discipline and structure to meditate regularly and effectively; I've really enjoyed using this feature of the app, among its many others.

Having very little help from my doctor I was left to research for myself which can leave you confused. This app is very easy to use, full of the relevant information you need and tailored to you.
