Mobile applications (apps) offer a novel way to engage children in behavior 
change, but little is known about content of commercially available apps for 
this population. We analyzed the content of apps for iPhone/iPad for pediatric 
weight loss, healthy eating (HE), and physical activity (PA). Fifty-seven apps 
were downloaded and tested by two independent raters. Apps were coded for: 
inclusion of the Expert Committee for Pediatric Obesity Prevention's (ECPOP) 
eight recommended strategies (e.g., set goals) and seven behavioral targets 
(e.g., do ≥1 h of PA per day), utilization of gaming elements, and general 
characteristics. Most apps lacked any expert recommendations (n = 35, 61.4 %). 
The mean number of recommendations among apps that used recommendations was 
3.6 ± 2.7 out of 15, 56.1 % (n = 32) apps were classified as games, and mean 
price per app was $1.05 ± 1.66. Most apps reviewed lacked expert recommendations 
and could be strengthened by addition of comprehensive information about health 
behavior change and opportunities for goal setting.
