iSSH – the only iPhone SSH/RDP/VNC app you need
The name is misleading – this does SSH, but also RDP and VNC as well. In fact, just the RDP capability (Remote MS Windows Control) is far more powerful than a more expensive and popular RDP-only app I used to use.
I use this one app for all my Windows and Unix servers – from my home desktop to my media centre, RPi, and Amazon instances. It’s fantastic and excellent value.
