You can downloading anything like movies , music , softwares , TV serials , Books and many more on torrent and you can only download with the help of bittorrent software. You can download free of cost on play store for android. The functions are very cool like auto shutdown , download only on wifi , battery saver , auto start and you can control its downloading speed.
