A mobile phone food record app to digitally capture dietary intake for adolescents in a free-living environment: usability study.

ABSTRACT:

Background

Mobile technologies are emerging as valuable tools to collect and assess dietary intake. Adolescents readily accept and adopt new technologies; thus, a food record app (FRapp) may be a useful tool to better understand adolescents' dietary intake and eating patterns.
