• The Target detection and the actual goalmate and the most important part of the application associated with this is explained in more detail in the next section.

A user can enter their goal, tasks to be completed, a weekly interim goal, the target date, their motivation, supporters and a referee, among other things. The following values could be used as an example:

• Goal: I want to lose 5 kg.
• Intermediate goal: 0.5 kg less per week.
• Tasks: Swim, run, drink 3 liters of water
• Reasons: Is healthier, I feel more attractive, Necessary for the new job

The system calculates the number of weeks required to achieve the overall goal and creates an overview of the individual weeks and the interim goals to be achieved. A calendar is also available for creating tasks associated with this goal. This enables the user to enter tasks in a weekly scheme to help them achieve their weekly interim goal.

Following the divide-and-conquer principle, a large goal is divided into several small goals that need to be achieved. As an additional motivation, money can now be placed on oneself and this achievement by using the penalty payment procedure. In order to avoid incorrect results when evaluating this achievement (after all, people often lie to themselves), the user can choose their own referee - usually their best friend - who also gives a rating in addition to the user themselves. Depending on the outcome of the assessment and the choice of punishment, the system automatically enforces the penalty.
