I got this app because my water intake was incredibly low, (probably around 40 oz a day intake). After seeing this app I downloaded it excitedly and have used it ever since! It does a great job of calculating your water intake, super user friendly, hooks up to apple health, and the UI is incredibly sleek. My only suggestion is that it would be nice if you could customize the icon shapes of the drink containers. Otherwise, great app and Im happy that my water intake has increased dramatically.
