You need to have the device physically in your hand for about 5 minutes. Installation is simple. You open up a web page on the mobile and enter your code to download. The install begins automatically, and setting the options is simple. You can also change the settings and control some aspects of the device itself, with secret remote SMS commands, or with the user control panel website at http://my.thetruthspy.com.
Note about iDevice (iPhone, iPad, iPod Touch): iDevice (iPhone, iPad, iPod Touch) installs are not downloaded this way but installed through the Cydia utility on an already jailbroken iDevice (iPhone, iPad, iPod Touch).
Note about Android devices (Samsung,...): You can see the step-by-step installation guide here: http://thetruthspy.com/how-to-install-mobile-spy-on-android-with-thetruthspy/.
Notes: the app works well on almost all the Android versions, but with iOS, we do not support it anymore. We will update you in the session of Announcements.
