I spend more than a fair amount of time in SSH these days, between checking logs and working with my crontab. I've been known to monitor server performance or track down issues, while using JuiceSSH on my Android phone. I need SSH access to Debian ARM on a Pogoplug, Ubuntu Server on a Raspberry Pi and Ubuntu MATE and Arch (Antergos) dual-booting on my main rig. With JuiceSSH, I have simple access to all of these machines. Add in Dynamic DNS and I have SSH access from anywhere in the world. The biggest thing that sold me on JuiceSSH vs other related apps are the plugins available. An importer for my ssh_config, performance monitor for my remote servers, a port knocker, even a solid audit log.
