Develop a prototype of an app called "Flexible Diary"

The final aim of this project is to develop an app that runs on IOS and Android.
The app helps the user to find out which of his routines / behavior might have an effect on his health condition and his constitution.
The user is able to flexibly define his own categories and values below the categories.

In this app
(1) the user can do a documentation of his/her day while using different categories.
(2) there is an algorithm which recognizes correlations between the different values of the categories and makes a visual display of correlations. And gets smarter with each user entry.

For example: There is a correlation between "Food: strawberries" (cause) and "State of health: bad" & „Skin: very bad“ (result).
In general there are categories that belong to the „Cause“-Section and there are categories that belong to the „Result“ section.

Therefore the user has the following defined categories:

1. Health constitution (Result Section) (max. 4 categories with max 5 values each)
1.1 General condition
1.2 Dummy
1.3 Dummy….

In Result Section the user can record only a single value for each category.

2 Specific symptoms (max. 8 categories with max 10 values each)
2.1 Category Head

2.2 Category Back

2.3 Category Dummy

2.4 Category Dummy


In Symptoms Section the user can record multi-value for each category.

3. Behavior/Routines (Cause Section) (max. 6 categories with max 10 values each)
3.1 Food
—> max values 10
3.2 Sports
—> max values 10
3.3 Stress factors
—> max values 10
3.4 Dummy
—> max values 10
3.5 Dummy
—> max values 10
3.6 Dummy
—> max values 10


In Behavior section the user can record single-value for each category.


The user is able to define his/her own name for the values for each of the categories.
The user is also able to define his/her own name for the category itself.
The maximum of Result categories is:

Doing the records for each day:
The user gets one screen where he/she can see the categories he/she wants to see as tiles.
The tiles of result section are optically separated from the tiles of the cause section.
The names „Cause“ and/or „Result“ section do never appear to the user.
The user can tab on the tiles in order to select it for entering the daily value.
The user chooses the value and confirms and returns to day overview.
The user repeats this for each category that is on his overview screen.

Editing his categories:
The user has a screen with an overview of all categories.
This overview has three different sections for (1) Result Section (2) Symptoms Section (3) Cause Section)
When tapping on on of the categories the user is able to edit the category name itself and each of the values belonging to this category.
The user can save edits or cancel edits.
If the user wants to save an edit the user needs to get a warning, that the analysis is resetted.
