Read full description

Mi Water is used to record your fluid intake, e.g. water consumption. For example, every time you drink a glass of water, you register it in the app. You can then later see a chart of how many glasses of water you have drunk. Please note that a paid subscription is required to register new data and to import data into the app. If your subscription expires, you will retain full access to all your existing data. Even without an active subscription, you can still browse your records, view them in the chart, and export your data for further analysis.
