From the developer:
PortX is a lightweight cross-platform SSH Client. With a simple but comprehensive UI, PortX gives you a pure terminal emulation experience. Google Drive syncing for session files across devices and OSes allows sysadmin and network admins to stay up to date wherever they are. Accessing and managing remote systems is an easy thing to do.
