New app aims to nudge hesitant smokers toward quitting
NCT ID NCT07459621
First seen Jun 27, 2026 · Last updated Jul 10, 2026 · Updated 2 times
Summary
This study compares two mobile health apps designed to help people who are ambivalent about quitting smoking. Both apps provide standard advice, but one includes extra content tailored for those not ready to quit. Researchers will track whether participants request free nicotine patches or quitline services, and if they report not smoking after 6 months.
