Habit Tracker

An Application whose goal is to help the user acquire new habits.

How?

Successes are to be reinforced by means of positive reinforcement via the accumulation of a streak. Various functions are used to actively track the new habits, as well as specific, informative outputs about the user's own success and a few analysis outputs.

Database

Overview

Data is created in a database using SQLite3. In order to use as little memory as possible and at the same time maintain simplicity, the data is overwritten per update - statement according to the actuality. Exceptions are losses of Streaks, which are not actively mapped but would be output via App-Command if desired. Relations between the tables are given by various FOREIGN KEY's.

The user creates various habits, specifying the frequency with which he wants to devote himself to them. If there is a failure to follow the set plan, the user is asked to explain how this failure occurred. Subsequently, the user must indicate his consideration or measure, which should contribute to avoid further fittings.

Tables

Habits

The table within which all data about the respective habits are stored.

habits
id	name	frequency	duration	checked_status	streak	reason_failure_id	avoidance_strategy_id	check_date	checked_timestamp
INT	TEXT	TEXT	INT	INT	INT	INT	INT	INT	DATETIME

The table within which the reason for each break of the streak is stored.

reason_for_failure
id	reason	habit_id
INT	TEXT	INT

The table within which the strategy to avoid further streak breaks is stored.

strategy_for_failure_elimination
id	strategy	habit_id
INT	TEXT	INT

The table within which data for the respective break in the streak are stored

meta_information
id	frequency	duration	streak	habit_id
INT	TEXT	INT	INT	INT

A linkage table between the reasons and the strategies

habit_reasons_strategies
id	habit_id	reason_id	strategy_id	meta_information_id
INT	INT	INT	INT	INT

Installation

pip install -r requirements.txt

Usage

The CLI "Typer" serves as interface. By means of simple app commands, the user can navigate through the app. Cosmetic adaptations of various outputs of the terminal were made with the library "rich".

python main.py --help

Depending on whether you run the application via IDE or terminal, you open the IDE's terminal or use your computer's terminal and navigate to the application's directory. With the command "python main.py --help" you start the application and get an overview of all functions. Depending on which action is to be executed, further instructions are given to the user via the terminal.

Tests

The pytest testing tool is used to test various functions within the app.

pytest .
