NCT ID NCT04309461
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a program that uses a smartphone app, an activity tracker, phone coaching, and rewards to help adults in rural Kentucky eat more fruits and vegetables, cut down on fat, get more exercise, and spend less time on screens. About 279 participants will use the app and track their progress. The goal is to see if this approach can lead to lasting healthy lifestyle changes and improve quality of life.
