EQ Software is a desktop product so to use it on a remote PC, an iPad or similar tablet you need a connection to a Windows desktop PC with EQ installed locally.
For a standard Windows desktop computer this will be a screen sharing remote control application.
There are multiple applications available which offers some simple remote access. Examples are Teamviewer, Chrome Remote Desktop or LogMeIn. You install it on a desktop PC and it runs ready for a remote connection. Note that a local user on the PC cannot continue to use the PC whilst a remote user connects at the same time.
Some of the above applications also offer iOS or Android apps to connect remotely. Note that as EQ is not designed for a mobile platform this is not recommended for long term use.
For dedicated remote use read the article on Terminal Services (with Remote Desktop).
