Yes i've used it via transdrone app for android, but it requires IP of PC and open port, which is a hit or miss to configure... It works sometimes, but mostly it fails, even after forwarding ports correctly...
Surely would love this feature! Been waiting for this from long time... Have to add torrent on utorrent whenever i am going out somewhere just because it can be controlled remotely... Makes a mess to use 2 apps for the same purpose of downloading torrents! :(
