Dont bother getting this app
Before the most recent update, it functioned as a video downloader. Now, its essentially useless. Not only do you need wifi to watch any videos in your playlists, but it is extraordinarily buggy, occasionally refusing to play while the phone is asleep, and restarting your progress in the video when you wake up your phone from the rare times that it works while asleep.
