Since 2010, Xiaomi has become one of the largest manufacturers of smartphones,
tablets,
fitness trackers, and
apps [8] The brand has been criticized
for spreading malware and spyware on its devices and
for secretly stealing user data without their knowledge or consent [9][10][11].
While the Microsoft Health requires a
fitness device such as Microsoft Band or a third - party
app for collecting data, the Google Fit can easily gather data through the built - in sensors of an Android smartphone or
tablet.
