In a world with so many unknowns, we can never be too sure about what to drink and when to drink it. With that in mind, we have developed the application, Walter – Drink Water Reminder, to help us track and remember to drink water at the right time. This app will remind you of the water you need to drink in order to keep your body in a healthy state.

Walter will track your daily consumption of water and automatically calculate the amount you need to drink in order to reach your daily hydration goal.

This app can also help you keep track of the amount of water you have consumed and how much remains.
