In times past, searching for and finding people were challenging and difficult especially with the absence of modern
communication gadgets. With the emergence of cellular technologies, locating people has been much easier and
mobile phone users can easily be reached by calling their mobile phones. With the emergence of various networkbased
positioning techniques and Global Positioning System (GPS) locating people via their mobile devices with or
without their knowledge has been a lot easier through Location Based Service (LBS) systems. LBS provide location
dependent services to mobile users and therefore becoming a need in the present ubiquitous world. Intelligent
Tracker (IntelTrack) is a mobile application that helps to track the current location of the mobile device and other
devices with built-in GPS via their International Mobile Equipment Identity (IMEI) number with the sole purpose of
locating the user and providing location dependent services. The application was deployed on Java enabled phone
that has GPS chipset installed. “IntelTrack” a location based service (LBS) is based on Java 2 Platform, Micro
Edition satisfying the Java Specification Requirement for Location (JSR 179) and Java Specification Requirement
for Wireless Messaging (JSR 209). The LBS assists users recognize their location and in effect retrace their steps
when they are in a new or unknown environment especially with the prevalent security issues in the world. The
development toolkit was Java ME Platform SDK 3.0; it enhances execution of preverified java class. The result
show that “IntelTrack” was able to locate the mobile device with less than 0.4 meter accuracy.
