Apple has a strict policy on iOS apps that come with any mention of the BitTorrent file transfer protocol. Even if BitTorrent is not illegal by itself, Apple doesn’t want its name to be associated with it. Apps that had found their way past the app review team and into the App Store were quickly removed from sale. It happened with IS Drive in October.
iControlBits by developer Luka Hlastec is a native mobile client for popular BitTorrent app Transmission, available for Mac, Windows and Linux users. Transmission, by default, allows you to check on active downloads using a mobile web interface that’s accessible from iOS devices, but it doesn’t have an official app in the App Store. iControlBits, a native front-end that relies on Transmission’s RPC protocol, offers a faster alternative to the web view and it lets view ongoing transfers, pause and resume downloads and even browse active downloads to a NAS server remotely. You can’t initiate new downloads from the app, but the developer says he’s working on it for a future update. In an interview to TorrentFreak, the developer admits he created the app mainly for himself as he didn’t like the way Transmission for Mac let you see downloads through a slow webapp. iControlBits, however, allows you to change and set speed limits without having to use Transmission on the desktop; all you have to do is enable remote access.
It is unclear whether or not Apple will pull iControlBits from the App Store, but if you’re in need for a remote Transmission client to manage your torrents, go download it now. The app is available at $1.99 in the App Store.
