LiftYourself: A Health Promoting Mobile Application

With the aim of promoting a healthy life with respect to physical activity and nutrition, this paper presents an attractive mobile application that engages the user on three directions. It proposes readymade fitness training sessions that target specific body areas, with the possibility to customize them as the user sees fit. The app allows the user to keep track of the nutrients consumed daily with respect to an ideal ratio that fits the individual profile of the user. Finally, menus are proposed to the user. Interactivity is supported by the incorporation of a speech based chatbot, developed using the IBM Watson technology. A questionnaire based usability study was conducted and measured the satisfaction level of the users that used the app, as well as gathered suggestions for improvement. This application has the potential to be extended for a wide range of uses, including clinical, preventive, public health or rehabilitation.
