PRO Upgrade

To be able to use some of the app features purchase of upgrade is required.
Keyboard & Trackpad
When you sit on the couch or lying in your bed handling regular keyboard & trackpad is not very convenient right? So just use your iPhone or iPad to replace them.

Apps
iTunes Remote app by Apple is useless if iTunes isn't running on your Mac - launch it from your iPhone/iPad. Using Kodi or Plex - you can launch those too. Control apps installed on your Mac: launch, quit (immediately or with delay).
System
Have full control of your system: Restart, Sleep, Logout, Lock and much more. No need to stand up to turn off your display, just use your device and stay in bed.
