Using the app is as simple as accessing the video that you're interested in on the "browser" that comes integrated in the app itself and touching the green arrows that you'll see located on the bottom part of the screen. At that moment you can select the video quality you want to download. It normally has many different resolution options adapted to the different Android devices compatible with the application. The downloaded videos will be stored on your SD card by default, but you can move them around from one location to another, however suits you best.
