What's the difference between uTorrent and BitTorrent apps from the same developer? In Play Store, there are two apps with almost same descriptions from same developer: uTorrent and BitTorrent. What's the difference between them?
Effectively nothing. The two desktop torrent clients, uTorrent and BitTorrent used to be developed by two separate groups. Late 2006, µTorrent was purchased by BitTorrent Inc. Since then, they started shipping BitTorrent as a re-branded uTorrent, but also kept uTorrent around. Wikipedia

Because of this, they maintain one program, but have two versions separated only by name, and it seems as though they carried this over to their Android apps as well.
