NCT ID NCT05951088
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing a mobile app called Cardio2U for people with atrial fibrillation or heart failure. The app helps patients track their condition, learn about their disease, and communicate with their care team. Researchers will check if patients find the app easy to use and if they stick with it over time.
