Daily statistic

Daily statistics screen presents the analysis of the confirmed meals of the day. Numerical data is presented in various ways:

1. Color of the day – using the analogy with traffic light, red colored day indicates unbalanced nutrition and unhealthy eating habits. Green colored day, on the other hand, indicates balanced nutrition and healthy eating habits.

2. Occupation image – the main purpose of the application is to encourage people to adopt healthy eating habits. The change of figure image and status tries to inform the user what do his eating habits and food choices mean in a long term. Exceeding energy values for example reflects in progressive weight gain (therefore the image of over-nourished or fat person appears) on the other hand lack of energy intake suggests the possibility of malnutrition (therefore the image of a very slim and sick looking character appears).

3. Information about skipped meals

In addition the daily statistic view includes:

1. Quantities of consumed water

2. Information of energy (expressed in kcal or kJ), macronutrient (expressed in grams), salt (expressed in grams), sugar (expressed in grams) and saturated fat (expressed in grams) intake. On the right side of the actual consumed quantities, recommended values are listed.

3. Special diagram which shows the differences between the actual energy and macronutrient intake and the recommended one.

4. Basic information about health risks that inappropriate eating habits and bad food choices represent.

5. The type and duration of exercise needed to spend the exceeded energy intake.

7 day statistic

The weekly statistic view offers you information about the days you achieved the recommended nutrition as well as information about the days when inappropriate food choices were made.

The application allows you to follow the distribution of individual values of energy, macronutrients and water intake achieved per day or per last seven days.

You can easily move between weeks by using the slider. The data is represented in a graph that enables you to monitor your nutrition status – e.g. in progress, in stagnation, in decline…

This screen is also accessible through the "Menu" button.

Individual measurements

The application offers you to keep track about your individual measurements such as weight, height, etc. All entered values are stored in the statistics, thus you can observe how your personal measurement's values vary through time.

By clicking on a particular measured value, the screen slightly shifts down and a diagram of measured values on a time scale is displayed.


The calendar gives you an overview of the application usage. By clicking on the "Calendar" button, a window with a monthly calendar is displayed. The days are colored in green or red, depending on how appropriate was the dietary intake for that day. Red colored days indicate unbalanced nutrition and unhealthy eating habits, while green colored days indicate balanced nutrition and healthy eating habits. If for a particular day no data about meals was recorded, the day is colored grey.

By clicking on the red or green colored days, you can access the Daily nutrition status window.

Clicking on the gray colored days will return you back to the home screen where you will be able to enter the data for that selected day.
