ISG Iadov is an application designed to facilitate the precise measurement of the level of user satisfaction in research contexts, social studies, institutional projects or private initiatives. Although it is inspired by the conceptual structure of the Iadov method, this tool has been developed with a specific focus on the calculation of the Individual Satisfaction Index (ISI) and the Global Satisfaction Index (ISG), adapting them to contemporary and multidisciplinary contexts.

The application allows participants' responses to be recorded through a simple, intuitive and efficient interface, generating automatic results and interpretable graphs that reflect both the level of individual satisfaction and the global trends of the evaluated group.

Among its main features are:

• Automatic calculation of the Individual Satisfaction Index (ISI) and Global Satisfaction Index (ISG).
• Clear and understandable visualization of the results.
• Export of results for subsequent analysis.
• Versatile use in academic research, institutional evaluations, opinion surveys and studies of perceived quality.
• Friendly interface adapted to non-technical users.
• Management of multiple projects.
• Integration with Google forms.

ISG Iadov is a reliable and versatile solution that allows researchers, teachers, evaluators and professionals from different disciplines to collect, interpret and present data on the perception of satisfaction in a structured, clear and efficient way, adapting to both exploratory studies and formal research.
