I've only used Transdroid with Torrentflux-b4rt, and with that it's only able to see what's currently transferring, start and pause torrents. I think with other clients you get more functions, but this is all I need for now. I'd give it 3/5 as is. 5/5 if it had total control over Torrentflux-b4rt. I'd recommend this app for remote monitoring and, when applicable, controlling your torrent software.
