You can set your own drinking reminders within the Hydration feature on the main dashboard of the app.
The reminders can be set at a 2-hour interval throughout the day. There is also an option to have the notifications turned on only on certain days while excluding others when reminders are unnecessary.
To avoid notifications during your time of rest and to not be disturbed during sleep, you can set your awake hours within which the notifications will be available and will alert you to drink more water.
Once you save your reminders the app will send you notifications to drink more frequently in order to develop a healthy hydration habit.
