I thought I would have paid the money for the app for free. I have first installed on the smartphone, there is obtained - if the app description does not fully read - no indication that the app must be installed on your smartphone, as well as on the stick. In the opposite case, when you install on the stick, this notice is available in Settings. That should be maybe considered by the developer.
Is the app but once installed on both devices, then it makes best services. Opening sideload apps and standby function are reached much faster, and it can also serve Apps, in which normal remote control can not be used.
