Currently, different web tools are available for determining the decision-making power of an individual. The tools determine the decision-making capacity based on certain questionnaire. The authors have developed a multi-level android application called 'RAY' which helps to determine the decision-making power of the user. The software uses the user's textual response as an input. At the initial stage, the user goes through several questions based on the decision making and responses are recorded accordingly. In the next stage, the user is challenged with a multi-level game. Then, for a particular scenario, the user is asked to rate himself on 1 to 10 scale. The App records the user input at each stage. Based on the responses, it determines the decision-making capacity of the user whether it is strong, moderate or weak.
