Abstract: This study addresses the absence of design standards for cognitive training apps catering to seniors with mild cognitive impairment (MCI). Integrating qualitative and quantitative methods, it employs grounded theory (GT) for synthesising user interview data and iteratively refines design criteria through theoretical coding. The fuzzy analytic hierarchy process (FAHP) and criteria importance through intercriteria correlation (CRITIC) objectively establish weights for design evaluation criteria and finalise the weighting values using the combined ideal point assignment method. The VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) is used to evaluate and select design solutions. This comprehensive approach minimises subjectivity and bias in criteria determination and weighting, enhancing the Objectivity and accuracy of cognitive training application evaluations. Usability questionnaires and user testing validate that the integrated approach improves design decisions' objectivity and scientificity, making the application more responsive to user needs.
