Can you install bitTorrent apps on your iPhone?

Thanks

No because Apple doesn't allow that sort of thing into their restrictive walled garden. Apple thinks bittorrent might be used to download movies and music and Apple would prefer you to line their pockets by purchasing those movies and music from the iTunes store.

Android has a more open and creative ecosystem that doesn't have torrent clients.

There are some browser based extentions that can serve as bt clients. But i don't know if any will install on mobile browsers.
