Water affects all processes in the human body, so it is very important to monitor what we drink and maintain water balance in the body. We deliberately did not overload the application by entering various drinks. We have deliberately limited your data entry to three categories. This includes water, healthy and unhealthy drinks. We are sure that you can easily determine which category the drink you are drinking belongs to. Healthy drinks are any natural sugar-free drinks. Unhealthy drinks include alcohol and any sugar-laden drinks. The application allows you to control the following parameters: - water consumption should be at least 60% of the total volume of liquid drunk. - water and healthy drinks should be drunk not less than the selected norm. - it is advisable to exclude unhealthy drinks from consumption.
