MyDration helps you to keep track of your daily water intake. You can choose your target, or let MyDration suggest an amount, and then record whenever you drink. MyDration can also use data from Apple Health to adjust your daily intake, based on your activity level.
If enabled, MyDration will also provide you with reminder notifications when its time for you to have a drink.
MyDration provides an iPhone widget allowing you to see your progress towards your target at a glance.
MyDration also provides an Apple Watch app providing easy access to your current progress without having to get out your iPhone.
