 Based on the data sets acquired from the FitBit and Apple devices, a synthetic data set was created to depict a possible murder scenario.
 The timeline follows a period of 1 hour, and the victim’s steps count, heart rate, and active energy data is considered.
-In figure ????, 5 specific incidents have been highlighted which are crucial for the timeline of the case.

 The FitBit Alta HR is primarily paired with an android phone for this project using the FitBit mobile app. The app dashboard displays the number of steps, heart rate, distance travelled, calories burned, and active minutes as recorded by the wearable. The app also displays the daily summary of the data in a graphical format for easy understanding.

	The PurePulse [10] is the continuous and automatic heart rate tracker used by FitBit. The sensor uses the principle of photoplethysomography, like the Apple Watch (Section 2.2.2). However, unlike the Apple Watch, the PurePulse sensor is capable of continuously monitoring the user’s heart rate during an activity and the resting heart rate too.
