  Nowadays, Malaysian are so concerned about their body health. In respond to
this, this study proposed a conceptual prototype called vTracker to assist its
users to have a healthier body. vTracker is a web-based mobile application
which helps users to self-monitor their dietary intakes and workout activities
in a few simple steps. A research framework has been proposed using the Unified
Theory of Acceptance and Use of Technology (UTAUT) model to understand the
level of users' intention to adopt vTracker in Malaysia. Data was collected
from 206 respondents in Malaysia using survey method. Based on the result of
the analysis, it was found that respondents agree to subscribe to the system.
It addition to that, it was found that the three factors have a positive impact
on users' intention to adopt vTracker. These mentioned factors are performance
effort expectancy (PEE), social influence (SI) and facilitating condition (FC).
These significant factors are used for designing vTracker portal.
