Tvshowsapp: Easiest way to download your favorite shows automatically..shhh

Damn.. was excited about this until I saw it was mac only. I used to use RSS subscriptions for torrent but those went the way of the buffalo a while ago... so now i'm forced to do it manually every day.

I don't understand why this exists when SickBeard is much better and is written in Python with a web interface so it's platform independent.

This is on HN because...?

(I live outside the US) I wonder: are these downloads legal? Or some, maybe?

Thanks for this!
