Abstract Background Childhood obesity continues to grow in industrialized and developing countries becoming one of the major public health crises worldwide. This, in turn, causes short and long term financial and psychosocial burden to individuals and society. However, obesity can be prevented and reversed by changing one's diet. Previous studies showed that children who have a balanced diet rich in a variety of fruits and vegetables are less likely to be overweight and obese. Smartphone apps could be a useful tool for encouraging healthy eating behaviour and hinder obesity. The aim of this study was to evaluate children's experience of using a smartphone app designed to encourage healthy eating among 9-13 years old children. Methods According to dietary recommendations a smartphone app “Food Boss” was developed. The app consists of several different parts designed to promote healthy eating habits and knowledge about a balanced diet. A food diary, games, and the possibility to interact with peers were included. Children were asked to test the app for 2 weeks. Afterwards, two gender-specific focus groups were conducted. Results Children found the app easy to use and expressed a positive attitude to the user interface design. The app was perceived as being useful for learning about healthy eating and remember to eat more fruits and vegetables. User's engagement, interest and general satisfaction of using the app varied among the children, boys being more positive about their experience than girls. Though children asserted using the app in the future and recommending it to their friends. Suggestions for further app improvement was also disclosed. Conclusions Children's overall experience of using the app was overall positive and they found it useful for learning about healthy eating. Key messages Childhood obesity can be prevented and reversed by changing one’s diet. The “Food Boss” app can be an attractive way of reaching children and useful in encouraging healthy eating among children. Children’s overall experience of using the app was overall positive and they found it useful for learning about healthy eating.
