The comparative analysis of travel apps, although interesting, has only a conditional influence on the actual design of a survey. To achieve maximum performance in identifying stress points, the survey should have been complemented by interviews or real user tests on people's difficulties, not just inspired by existing tools. Relying solely on market analysis is like diagnosing a Wi-Fi problem by only looking at management apps, without ever checking the router itself. A rigorous cross-validation is essential for truly useful results.

A Google Forms survey with only 78 responses from adults is a bit light to confidently claim that 75% of people check their ID papers weeks in advance.

If a mutual or a consumer association had conducted the study with a representative sample, we might believe it a bit more, but here it smells like a commission to justify a service.
