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.

The sleep meditations have been very useful to help me fall asleep and I'm now sleeping through the night without waking up like I used to. Recommended 💯

My anxiety has reduced so much and I feel more optimistic about life.


App Store Review

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.

This is a great app for people who want to have data on their health and education to improve every aspect of their life.
