On the go means anywhere you have internet. I once set my PVR to record a show while I was a few provinces away. I'm not sure if the app works outside of Canada. If it doesn't you can use the website instead. The website gives you a few more options not found on the PVR/On the go app.
In the description for this app, they boast that you can set recordings when away from home with your smartphone. Not possible since the app needs to be connected to your home internet network, I guess you could technically be outside your house and still on your network. I am on vacation still in province and want to set a recording but the app constantly crashes on multiple devices. I am not trying to view programming, but simply set to record
