Core Graphics Sample App // by Ray Wenderlich
Introducing Flo.W – an app to track your drinking habits.
Specifically, it makes it easy to track how much water you drink. “They” tell us that drinking eight glasses of water a day is healthy, but it’s easy to lose track after a few glasses. This is where Flo comes in; every time you polish off a refreshing glass of water, tap the counter. You’ll also see a graph of your previous seven days’ consumption.
Coming soon when completed XD
