Eurzotmin

Eurzotmin is a decision-research application centered on personal preferences, linking option selection, actual expenditures, and usage feedback into a cohesive record. Users can structure research projects based on their specific criteria, logging costs, time investment, and experiential evaluations. By performing pairwise comparisons, users establish preference weights, with the app automatically checking for logical inconsistencies in these comparisons. The application provides ranked options, cost-versus-time scatter plots, filtering based on dominance relationships, and detailed calculation breakdowns. It also allows for simulations—adjusting prices, usage frequency, or preference weights—to observe how the "leading" option might shift. Once a decision is saved, the original parameters and rationales remain preserved; users can subsequently input actual costs, usage frequency, and satisfaction levels to compare expectations against reality. Any missing data is explicitly flagged rather than being automatically filled with zeros. All research data is stored locally on the device, with support for importing and exporting expense tables, as well as full backup and restoration, facilitating the long-term tracking of the rationale behind one's decisions.
