Abstract
Persuasive mobile health apps are types of information systems that are aimed at motivating or
encouraging people towards a pragmatic approach at an improved quality of life. The app store
market is gradually becoming saturated with numerous types of mobile apps and designing apps
to be persuasive in nature is a novel way of attracting and encouraging more users to access and
use such apps. Hence the main aim of this work is to design a cross platform persuasive mobile
health application called StayFit. The app was designed from the extended Persuasive System
Design (PSD) model and evaluated using the same model qualitatively. The app was also
developed using Cordova platform, Windows Operating System, Android studio, MySQL
database, Apache Server, Node.js, PHP, Bootstrap, Phonegap, Apache ANT and jQuery. The work
provides an approach for developing cross-platform applications in order to target a wider range
of platforms and the mHealth persuasive app developed is able to assist users maintain a healthier
lifestyle. The usability of the developed app was compared with existing apps using the Analytic
Hierarchy Process (AHP) model. Comparison was done using a group of 5 users with a usability
model and evaluated with the AHP-OS. Results of analysis showed that StayFit ranked the highest
with 48.4%, MyFitnesPal with 28.7% and Lose It with 23.0% while consolidated group
Consistency Ratio was 4.9%. It is recommended for further studies that the app be compared with
more apps in its category and evaluated using other Multi Criteria Decision Making (MCDM)
techniques. The usability of the app can also be determined using appropriate usability models and
techniques.
