In some projects, I really need quick access to a shell. I have an iPad, and wanted a terminal emulator on it. Bam. vSSH Lite is a universal iOS app available on Apple’s App Store right now for free. It is ad supported, but supports several awesome features, such as bookmarking, password saving, and copy / paste. If you wish to opt for the paid version, you are granted the absence of ads, and a lot of other goodies.
It’s the best SSH app for iOS, bar none.
