uTorrent has turned crappy over the last couple of years. It’s littered with ads, and bundles a ton of adware with the installer. It’s time you ditched it for much better alternatives
qBittorrent is open source, fast, and looks a lot like uTorrent. It’s easily the best torrent app for Windows.
Mac OS X
Transmission has a very simple interface that you should have no problems adjusting to. Just like qBittorrent, it’s open source and free of any ads.
Flud is a gorgeous torrent app for Android.
