What's the best app to download movies for free?

There's a very fast and simple way. Use utorrent. You can download it from the website for free. Then log into www.yify.com, search for a movie, and download the torrent file. Open the torrent file using utorrent, choose the download path, and start downloading.... that's it ! P.S. I have downloaded almost over 150 movies using utorrent!
