Prompt 2 is version 2 of a very good looking, easy-so-use SSH client for iOS. It's from Panic Inc, the people who brought us the excellent Transmit FTP client. As the website says, "Restart your server from a coffee shop. Fix a web page from the back of car..." Version 2 has several new features, notably Panic's sync across devices, iOS 8 compatibility, stored text in "clips", private keys, and easier switching between multiple connections. Sysadmins who must be able to access their servers remotely, securely and with first-class software will want to have this on every iOS device. Best of all? It's only $10.
