I tried the app on 7 day free trial. I didn't find it usefull, as it was asking me to track my water and to drink more - which I haven't had a problem with in the first place, as I drink enough water. this app is not for me. The problem with this app is I CANNOT CANCEL IT!! not in the app, nor via Play store in Google, they charged me 69.99 without me even having a chance to cancel. I sent them an email requesting refund and cancelation. Hope they have helpful customer service.
