Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
\- Does the gamified app version that delivers behavioral nudges have a higher adherence and acceptability rate, and does this translate to better dietary behaviors?
Participants will use either the intervention app (dietary assessment + gamification) or the control app (non-gamified, dietary assessment only) for six weeks to record all their food intake. Diet quality will be assessed at baseline and endline, and a Likert scale acceptability questionnaire will be administered at endline.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Intervention group- Gamified app version; dietary assessment + gamification
Participants will be randomly assigned at enrollment to the intervention group, which will receive a gamified app that delivers behavioral nudges and provides a daily report of caloric and nutrient intake.
A mobile application that uses AI to deliver behavioral nudges that encourage healthy food choices.
As a mobile application for assessing dietary intake, the app provides a daily report of food intake- a core function that both the gamified and limited app versions have. The gamified version has the added functionality of delivering behavioral nudges that encourage healthy food selections.
Control group- Limited app version, dietary assessment only
Participants will be randomized at enrollment to the control group, which will receive a "limited" app version that only provides a daily report of caloric and nutrient intake, without delivering behavioral nudges.
Limited app version for dietary assessment only
This app version provides a daily report of energy and nutrient intake- available to those randomized to the control group
