When I click the link provided in the manual to download Unity Remote 4 on iOS, it pops open iTunes which says "The item you've requested is not currently available in the U.S. store." Also, searching for "Unity Remote 4" on the App Store on my device turns up nothing from Unity Technologies.
I'd build it myself, but I don't yet have an iOS Developer Account.
