Works via IR or WiFi. (∩｀-´)⊃━☆ﾟ.*･｡ﾟ
There are 3 types of users for this app.
WHICH ONE IS YOU?
USER 1 - you lost your remote and can't connect to the home WiFi = you can use the IR mode, it does not require your Roku to be connected to your home WiFi, but you do need to have an IR sensor built in your phone. if your phone is not IR capable, you can buy an external IR sensor for a few bucks and the app can then control your Roku (instructions on what to buy exactly are inside the app).
USER 2 - Your Roku is already connected to your WiFi network, you want to use the best Roku remote available - use the WiFi Smart mode to connect to your Roku box - works on every phone. comes with a touch-pad and keyboard for your lazy fingers
USER 3 - you are bored and downloading apps for no reason - I feel you (စ‿စ )
