It really helps me keep track on how hydrated I am. The app is organized in a way that makes it really easy to use. I love that with just one touch you can choose precisely how much water you drank and validate the entry (you need to get it in order to fully understand how different and easy this feature is). Anyway I hardly review any app, but I had to review this one because I highly recommend it to anybody. Excellent job developers :)
See about iDrated Water, v1.2
