Design outcomes

Primary

Measure	Time frame
The feasibility of the FRANI will be assessed by measuring outcomes related to adherence and acceptability: 1. Adherence is defined as the number of days the participants completed dietary recalls on the FRANI divided by the total number of days of the pilot test. Participants will be considered adherent if this is equal to 70% or higher, starting to count from the first and ending on the last day of the pilot. 2. Acceptability summarizes likeability, satisfaction, intent to use, and intent to continue using the FRANI, while usability summarizes what affects the use of the FRANI. Acceptability and usability are measured according to answers from structured questionnaires. If participants grade the acceptability or usability of the FRANI as 30 or more points in their respective structured questionnaires, the app will be considered accepted or usable.	—
