New app could let cystic fibrosis patients skip some clinic visits
NCT ID NCT06147778
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a smartphone app called MuCopilot that helps people with cystic fibrosis measure their lung function and exercise ability at home. 70 adults in France used the app to perform tests like speaking into the phone and timed walks, and researchers compared those results to standard clinic tests. The goal was to see if the app provides reliable data that could reduce the need for frequent hospital visits.
