The resulting FoodSwitch mobile phone app was launched in Australia in January 2012 and was downloaded by about 400,000 users in the first 18 months. FoodSwitch has maintained a 4-plus star rating, and more than 2000 users have provided feedback about the functionality. Nutritional information for more than 30,000 additional products has been obtained from users through a crowdsourcing function integrated within the app. Conclusions: FoodSwitch has empowered Australian consumers seeking to make better food choices. In parallel, the huge volume of crowdsourced data has provided a novel means for low-cost, real-time tracking of the nutritional composition of Australian foods. There appears to be significant opportunity for this approach in many other countries. %M 25147135 %R 10.2196/mhealth.3230 %U http://mhealth.www.mybigtv.com/2014/3/e37/ %U https://doi.org/10.2196/mhealth.3230 %U http://www.ncbi.nlm.nih.gov/pubmed/25147135
