This is remote control app which allows you to control your Samsung Smart TV over the local network. It's similar to the new Samsung Smart Touch bluetooth remote like TM1360A, but with the help of your phone/tablet it works also with older TV models which do not have touchpad.
The purpose is not to replace the original remote, but it is handy in emergency situations (empty batteries, lost etc). This app has keyboard support that lets you type on your device and then send text to your TV. It's far more convenient then the original solution (choose letters on the TV's screen one by one). And of course this app has gestures. If you like gestures, then maybe you like this app too.
